Principle: Sawyer-Tower measuring system is used in hysteresis measurement which measures data by measuring voltage drop across the sample. The Sawyer-Tower measuring system uses sense capacitor which is replaced with circuit in the virtual ground measurement system. Therefore virtual ground measurement has more accuracy. The virtual ground measurement consists of amplifier and Integrator circuits. The precision DRIVE terminal is connected to the sample and RETURN terminal is connected to transimpedance amplifier with a virtual ground potential. Alternating voltage is applied to the sample through drive terminal results in polarization which leads to charge. The charge flow the sample due to applied DRIVE voltage is collected by the Integrator circuit whose measured output voltage translated to the Vision software. Errors are rejected in the measurement because of DRIVE and RETURN circuit matching with respect to speed and current sinking ability. The advantages of the virtual ground measurement system are; back voltage of sense capacitor is completely avoided and the charge developed by parasitic capacitance is made zero due to its association with RETURN port.
Application: Electric Field vs. Polarization Measurements of bulk samples.

Principle: AAS quantitatively measures the concentrations of elements present in a liquid sample. It utilises the principle that elements in the gas phase absorb light at very specific wavelengths which gives the technique excellent specificity and detection limits.The sample may be an aqueous or organic solution, indeed it may even be solid provided it can be dissolved successfully. The liquid is drawn in to a flame where it is ionised in the gas phase.Light of a specific wavelength appropriate to the element being analysed is shone through the flame, the absorption is proportional to the concentration of the element. Quantification is achieved by preparing standards of the element
Application: Identification of trace elements like Fe, Copper, Zince, Manganese, Lead, Mercury

Volumetric counting and continuous sampling
Principle: The basic principle of flow cytometry is the passage of cells in single file in front of a laser so they can be detected, counted and sorted.Cell components are fluorescently labelled and then excited by the laser to emit light at varying wavelengths.The fluorescence can then be measured to determine the amount and type of cells present in a sample.Up to thousands of particles per second can be analysed as they pass through the liquid stream.A beam of laser light is directed at a hydrodynamically-focused stream of fluid that carries the cells. Several detectors are carefully placed around the stream, at the point where the fluid passes through the light beam. The detectors therefore pick up a combination of scattered and fluorescent light. This data is then analyzed by a computer that is attached to the flow cytometer using special software.
Application: immunephenotyping, cell counting,apoptosis, cell cycle, DNA damage, proliferation analysis,etc
