Most common problems with gas chromatography

European Gas Chromatography Users Study, 1998.



"... BIP nitrogen used as a makeup gas for ECD increased baseline stability and produced lower background and 30% higher detector response. Similarly, using BIP helium ... for GC-AED, we found a more stable baseline for carbon ... as well as oxygen ... compared to 6 9's helium."

—Dr. Frank David, Research and Development Manager for the Research Institute for Chromatography (R.I.C.) in Kortrijk, Belgium

(Read the testimonial, "Up to 30% Higher Response in GC with Gas from Air Products' BIP Cylinders")

In a survey of GC users conducted in 1998 by LC-GC International, almost 70% of the respondents identified contamination, poor resolution (interpreted as decreasing resolution due to stationary phase degradation), stationary phase bleed, and ghost peaks as their most common GC column problems. All of these problems can be caused or aggravated by impurities in the carrier and detector gases.

Because the BIP cylinder consistently delivers gas containing less than 10 ppb oxygen and less than 20 ppb water, it can enhance analytical performance by maintaining peak resolution, improving detector sensitivity, decreasing baseline rise, and producing an artifact-free baseline. Sometimes these improvements are more incremental than dramatic, since there are many potential contributors to contamination of the carrier gas flowing through a GC column. But BIP gases allow you to make even small improvements in your analytical system and reap the benefits over time.


"We're very pleased with the BIP technology ... We're getting better analytical performance at a very reasonable gas cost."

—Paul Knowles, Analytical and Environmental Services Ltd. (AES), UK

(Read the testimonial, "BIP Technology Saves Time and Money at AES")
"In addition to cost savings are the performance advantages of reduced baseline noise, limits of detection, and improved resolution with the BIP technology."

—Dr. Anthony M. Edge, UK Laboratory of the Government Chemist [LGC]
