PRINCIPLE OF HPLC Fig. 1 Schematic layout of a HPLC system The separation principle of HPLC is based on the distribution of the analyte (sample)

High performance liquid chromatography (HPLC) is very popular and widely used in the pharmaceutical industry but is also an important tool for the analysis of

HPLC system care and troubleshooting is an important activity in any analytical chemistry lab. Liquid chromatography systems have become real workhorses for laboratory chemical analysis,

Even the most carefully executed experiment can give erroneous results if dirty glassware is bought to use. If the glassware that is used for measuring

Almost every laboratory uses chemicals and reagents in one form or another. Knowing where to buy them, what grade to purchase, and what labeling is

What is Biosafety: The application of knowledge, techniques and equipment to prevent personal, laboratory and environmental exposure to potentially infectious agents or biohazards. Biosafety defines

If you have experienced retention time shifts with LC, you know it can be complicated and can cause problems with quantitation if not resolved. Hopefully

Nitrogen generators use a supply of dry, oil-free air to purify nitrogen via a selectively permeable membrane or carbon molecular sieve material which removes oxygen,

While you can drink tap water, it’s not suitable for most laboratory tests, preparing solutions, calibrating equipment, or cleaning glassware. For the lab, you want

In the last decade, inductively coupled plasma triple quadrupole mass spectrometry (ICP-QQQ), also called inductively coupled plasma tandem mass spectrometry (ICP-MS/MS), has been a game

UV Lamps have been there for more than a century. Apart from usual lighting applications, these lamps have been used in a variety of utilities

Laboratory workers and researchers must be cognizant that laboratory equipment can malfunction without adequate monitoring and regularly scheduled maintenance. Equipment typically does not undergo catastrophic

The procedure for the sampling and analysis of soils for volatile organic compounds (TPH GRO, BTEX, MTBE and naphthalene by GC, and volatiles by GC/MS)

Unplanned and unexpected instrument downtime in a lab means delays and frustrations that can potentially damage a lab’s reputation to reliably deliver high-quality results. Problem: Unplanned and

GC capillary columns are capable of consistent efficiency and high resolution provided adequate care is exercised during installation, conditioning and storage in this article some

Silica gel adsorbents are widely accepted as one of the best adsorbents that are used in column chromatography. One of the main benefits is that

Nitrogen is the 7th most abundant element found in our solar system and our atmosphere is made up of 80% nitrogen gas. Nitrogen is used
