Electrospray ionization (ESI)

Electrospray ionization (ESI) is a technique used in mass spectrometry to produce ions using an electrospray in which a high voltage is applied to a liquid to create an aerosol. It is especially useful in producing ions from macromolecules because it overcomes the propensity of these molecules to fragment when ionized. ESI is different than other atmospheric pressure ionization processes (e.g. MALDI) since it may produce multiply charged ions, effectively extending the mass range of the analyser to accommodate the kDa-MDa orders of magnitude observed in proteins and their associated polypeptide fragments.

Flow Cytometer

The FACS Aria III flow Cytometer from Becton Dickinson (USA) is a high speed cell analyzer and Sorter for measuring and sorting fluorescently labeled cells. Any Suspended cell form 0.2- 100 micrometers in size is suitable for analysis. When a fluorescent dye is conjugated to a monoclonal antibody, it can be used to identify a particular cell type based on the individual antigenic surface markers of the cell. In a mixed population of cells, different fluorochromes can be used to distinguish separate subpopulations. The staining pattern of each subpopulation, combined with FSC and SSC data, can be used to identify which cells are present in a sample and to count their relative percentages. The cells can also be sorted if chosen. For more information about the principles of flow Cytometry, please find below a link to a tutorial from BD Biosciences:

Gas Chromatography GC-FID

Gas chromatography (GC), is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. A flame ionization detector (FID) is a Scientific Instrument that measures the concentration of organic species in a gas stream. It is frequently used as a detector in Gas Chromatography.



Headspace GC is used for the analysis of volatile and semi-volatile organics in solid, liquid and gas samples. Analyses of alcohols in blood and residual solvents in pharmaceutical products. Other common applications include industrial analyses of monomers in polymers and plastic, flavor compounds in beverages and food products, and fragrances in perfumes and cosmetics.

Gas Chromatography-Mass Spectroscopy GC-MS

Gas chromatography-mass spectroscopy (GC-MS) is one of the hyphenated analytical techniques. As the name implies, it is actually two techniques that are combined to form a single method of analyzing mixtures of chemicals.

High Performance Thin Layer Chromatography HPTLC

High performance thin layer chromatography (HPTLC) is an enhanced form of thin layer chromatography (TLC). A number of enhancements can be made to the basic method of thin layer chromatography to automate the different steps, to increase the resolution achieved and to allow more accurate quantitative measurements.

Automation is useful to overcome the uncertainty in droplet size and position when the sample is applied to the TLC plate by hand. One recent approach to automation has been the use of piezoelectric devices and inkjet printers for applying the sample.

The spot capacity (analogous to peak capacity in HPLC) can be increased by developing the plate with two different solvents, using two-dimensional chromatography. The procedure begins with development of sample-loaded plate with first solvent. After removing it, the plate is rotated 90° and developed with a second solvent

Inductively Coupled Plasma Mass Spectrometry ICP-MS

Inductively coupled plasma mass spectrometry (ICP-MS) is a type of mass spectrometry which is capable of detecting metals and several non-metals at concentrations as low as one part in 1012 (part per trillion). This is achieved by ionizing the sample with inductively coupled plasma and then using a mass spectrometer to separate and quantify those ions.

 Compared to atomic absorption techniques, ICP-MS has greater speed, precision, and sensitivity. However, analysis by ICP-MS is also more susceptible to trace contaminants from glassware and reagents. In addition, the presence of some ions can interfere with the detection of other ions.

Nuclear Magnetic Resonance

Nuclear magnetic resonance, NMR, is a physical phenomenon of resonance transition between magnetic energy levels, happening when atomic nuclei are immersed in an external magnetic field and applied an electromagnetic radiation with specific frequency.  By detecting the absorption signals, one can acquire NMR spectrum. According to the positions, intensities and fine structure of resonance peaks, the structures of molecules can be studied quantitatively. The size of molecules of interest varies from small organic molecules, to biological molecules of middle size, and even to some macromolecules such as nucleic acids and proteins.

Personal Genome Machine

DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. It includes any method or technology that is used to determine the order of the four bases—adenine, guanine, cytosine, and thymine—in a strand of DNA. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery.

Knowledge of DNA sequences has become indispensable for basic biological research, and in numerous applied fields such as diagnostic, biotechnology, forensic biology, and biological systematics. The rapid speed of sequencing attained with modern DNA sequencing technology has been instrumental in the sequencing of complete DNA sequences, or genomes of numerous types and species of life, including the human genome and other complete DNA sequences of many animal, plant, and microbial species.


  • DNA sequencing may be used to determine the sequence of individual genes, larger genetic regions (i.e. clusters of genes or operons), full chromosomes or entire genomes. Sequencing provides the order of individual nucleotides in DNA or RNA (commonly represented as A, C, G, T, and U) isolated from cells of animals, plants, bacteria, archaea, or virtually any other source of genetic information. This is useful for:
  • Molecular biology: studying the genome itself, how proteins are made, what proteins are made, identifying new genes and associations with diseases and phenotypes, and identifying potential drug targets
  • Evolutionary biology: studying how different organisms are related and how they evolved
  • Metagenomics: Identifying species present in a body of water, sewage, dirt, debris filtered from the air, or swab samples of organisms. Helpful in ecology, epidemiology, micro biome research, and other fields.
  • Less-precise information is produced by non-sequencing techniques like DNA fingerprinting. This information may be easier to obtain and is useful for:
  • Detect the presence of known genes for medical purposes (see genetic testing)
  • Forensic identification
  • Parental testing.

Scanning Electron Microscope (SEM)

A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning it with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that can be detected and that contain information about the sample's surface topography and composition. The electron beam is generally scanned in a raster scan pattern, and the beam's position is combined with the detected signal to produce an image. SEM can achieve resolution better than 1 Nano meter. Specimens can be observed in high vacuum, in low vacuum, and (in environmental SEM) in wet conditions.

The most common mode of detection is by secondary electrons emitted by atoms excited by the electron beam. The number of secondary electrons is a function of the angle between the surface and the beam. On a flat surface, the plume of secondary electrons is mostly contained by the sample, but on a tilted surface, the plume is partially exposed and more electrons are emitted. By scanning the sample and detecting the secondary electrons, an image displaying the tilt of the surface is created.

The 7600F is a field-emission scanning electron microscope that magnifies up to one million times for visualization and imaging of nanoscale-sized objects.

The FESEM is equipped with an AZtec and INCA microanalysis system, the wide range of operating modes and detectors are optimized for surface imaging and analysis of materials at the nanometer scale.

Wavelength Dispersive X-ray Fluorescence Spectrometry (XRF)

Wavelength Dispersive X-ray Fluorescence Spectrometry (XRF) is one of the most widely used instrumental and analytical techniques. It’s used to determine the chemical composition and elemental concentration for different kind of materials in the concentration range of 1 ppm to 100%.

Xrf spectrometry is used for the bulk chemical analysis of materials in variety of applications in industry, in environmental studies and in academic research. In geological applications, xrf is mostly used for determining the major and trace element composition of rock and sediment samples. 

An XRF spectrometer uses primary radiation from an X-ray tube to excite secondary (fluorescent) X-ray emission from a sample which is usually in the form of a solid disc (fused bead or pressed pellet). The spectrometer is calibrated by measuring standards or reference materials and the calibration determines the relationship between the concentration of elements and the intensity of the fluorescent lines of those elements. 

Benefits of analysis by XRF:

  • Minimal or no sample preparation
  • Non-destructive analysis
  • Na11 to U92 analysis, ppm to high % concentration range
  • No wet chemistry – no acids, no reagents
  • Analysis of solids, liquids, powders, films, granules etc.
  • Rapid analysis – results in minutes
  • Qualitative, semi-quantitative, to full quantitative analysis
  • For routine quality control analysis instrument can be ‘used by anyone’
