Laboratory Water Purification techniques – their advantages and disadvantages
Water for laboratory use has been divided into different grades for different laboratory applications
Suitability of Laboratory Water Grades for different Laboratory Applications
A laboratory uses large quantities of water for numerous activities. Water grades for laboratory use discussed the different grades of water which are commonly used in the laboratory.
Laboratory use Water
Water grades for laboratory use have been discussed earlier.ASTM 1193 Laboratory grade specifications have been laid down for TypesI, II and III
Laboratory oriented training
A fully laboratory oriented training was conducted in our Trace metals analysis section for Mr Babangida Jungudo, Nigeria.
Water Grades for Laboratory use
The universal solvent character unfortunately makes water susceptible to contamination from different sources and different purification practices need to be adopted to achieve the required purity levels for different laboratory requirements.
Sample Injection Practices in Gas Chromatography
The accuracy and precision of your results will largely depend on reproducibility of injection volumes. Read more about Injection Practices in Gas Chromatography.
How Gas Chromatography can contribute to your career prospects?
Gas chromatography is an established and popular technique used for separation of components of a mixture of gases or liquids and help quantify them.
Gas Chromatographic response
A chromatographic detector serves to identify and quantify the sample components as they reach it in a sequence after separation in the chromatographic column.
chromatographic calculations
A typical chromatogram comprises of several peaks varying in size. The height of each peak is in proportion to the amount of the particular component present in the sample mixture injected into the chromatograph.
