Which is better option for quantitative chromatographic calculations – Peak height or Peak area ?

Peak area for quantification by chromatography is preferable to peak height as it takes into consideration peak shape distortions , if any

Professional Qualities that matter in your laboratory team

Team building in a laboratory setup plays a vital role as in any other commercial organization. As a laboratory in charge it is important for you to have clarity yourself on expectations you have from your team members. In other words you have to have a vision and roadmap ready on how you would like […]

Familiarize with the Gas Chromatograph

A Gas Chromatograph like any other analytical instrument has evolved from one with several knobs and dials to one having a simple microprocessor based keypad to control the operational parameters. The simplification has resulted in ease of operation and time saving. An understanding of the main component parts will help in maximum utilization of system capabilities.

Tips on improving accuracy and precision of Gas Chromatographic injections

The accuracy and precision of Gas Chromatographic analysis depends to a significant extent on your skill to use the injection syringe. It is possible to achieve a precision of manual injection volumes less than 1% RSD once you have gained mastery on sample injections. Proper handling and care of chromatographic syringes has been dealt with earlier. […]

Troubleshooting Tips for Gas Chromatographic Syringe

Gas chromatographic syringe is an indispensable accessory for the gas chromatographer. Syringe is necessary for introduction of selected volume into the gas chromatograph. The results of analysis are meaningful only if the selected volumes are accurately and reproducibly transferred into the system. Proper handling and care of chromatographic syringes has been covered earlier. However, in addition […]

Certificate Course on Gas Chromatography now available!

Finally the wait is over. Since the launch of our certificate courses on HPLC and Atomic Absorption Spectroscopy we have received several requests for a similar Course on Gas Chromatography. It has taken considerable time to develop the course as GC has wide-ranging applications in diverse areas and consolidation of details proved to be time-consuming. […]

Responsible Collection and Disposal of Laboratory Waste Materials

Laboratories are doing an immeasurable service to mankind and their contribution towards promotion of commerce and trade is well recognized. However, all the benefits offered by laboratories can get nullified if laboratory wastes are disposed irresponsibly and without concern for the preservation of our environment. Laboratory wastes are potentially hazardous as they can have the […]

Safe Handling of a Laboratory Desiccator

A laboratory desiccator is a round shaped closed vessel made of heavy glass which is a common laboratory glassware item and has multiple uses, such as: Storage of standards under dry environment Storage of materials for weighing to constant weight Prolonged storage of hygroscopic materials Determination of loss on drying of manufactured products such as […]

Role of HPLC in Cleaning Validation of Laboratory Glassware

HPLC has made significant contributions in detection and quantitative estimation of organic compounds. In pharmaceutical analysis HPLC has been extensively used in assay of the active ingredient as well as related impurities which are present in formulations in very low concentrations. Estimation of related substances was not possible using other conventional analysis techniques. This unique […]

Cleaning Practices for Laboratory Plastic ware

Laboratory ware should be free from contamination before it is put to use. Contaminated items can contribute significantly to analytical errors. Aspects of cleaning of laboratory glassware have been discussed in an earlier article. In recent years plastic ware has gained marked presence in laboratories and because of basic differences from glassware it requires a different […]
