New Technology for Extending HPLC Column Life and Improving Chromatography

HPLC and UHPLC are conventional analytical tools used in many labs to separate and analyze dissolved components in solution. Injection of samples containing particulate will eventually block the column inlet, cause high column back pressure, and shorten the normal lifetime of the column. Build-up of non-dissolved particulates on the head of the column, which continue to dissolve, can cause chromatographic interference including ghost peaks and baseline drift.

One solution to column plugging and chromatographic interference is sample filtration; but sample filtration is not without risk. One cannot be sure how much longer a column will last if filtration is used.

Pall Corporation has introduced a "next generation" syringe filter which can extend UHPLC column life over 100 times, while not causing interference due to extractables, even in methods as sensitive as LCMS. New column life testing will be reviewed as well as analytical interference in LCMS.

‘Smelling’ Prostate Cancer
A research team from the University of Liverpool and the University of the West of England (UWE Bristol) has reached an important milestone towards creating a urine diagnostic test for prostate cancer that could mean that invasive diagnostic procedures that men currently undergo eventually become a thing of the past.
Charting Kidney Cancer Metabolism
Changes in cell metabolism are increasingly recognized as an important way tumors develop and progress, yet these changes are hard to measure and interpret. A new tool designed by MSK scientists allows users to identify metabolic changes in kidney cancer tumors that may one day be targets for therapy.
Portable Kit Can Recover Traces of Chemical Evidence
A chemist at the National Institute of Standards and Technology (NIST) has developed a portable version of his method for recovering trace chemicals such as environmental pollutants and forensic evidence including secret graves and arson fire debris.
Diagnosis of Two Rare Childhood Diseases Improved
For the first time, researchers have developed tests that could improve the diagnosis of two rare childhood diseases known as congenital disorders of glycosylation (CDGs) and metachromatic leukodystrophy, and that could even lead to new treatments for CDGs.
