Application Notes: GC
EPA Method 537.1 - PFAS in Drinking Water
Strata-SDB-L and Luna Omega 1.6 µm PS C18 demonstrate excellent precision and recovery in EPA Method 537.1 for the analysis of PFAS in drinking water.
PFAS Analysis Using a pH-Variable LC Mobile-Phase Gradient
A novel LC approach to manipulate the chromatography of closely related PFAS analytes to separate co-eluties and avoid matrix interferences.
Air Analyzer for VOCs
An online thermal desorber has been developed for the automated, in situ, determination of VOCs. The system does not need liquid nitrogen or CO2.
Analysis of Volatile Organic Compounds in Environmental Samples
This e-book demonstrates the use of Purge and Trap coupled with GC–MS to meet the challenges of VOC analysis for the most common EPA regulations and methods.
Converting Your GC Carrier Gas
Learn how to convert your GC carrier gas from helium to hydrogen with this step-by-step guide to avoid the increasing cost of helium.
Syrup Differentiation with ChromaTOF Tile
GCxGC TOFMS analysis can be overwhelming, but ChromaTOF Tile can quickly compare these data sets to bring statistically significant differences to the forefront.
Helium and the Cost to Laboratories
What has happened over the last two years since the global helium shortage was the hot topic in GC, where do we currently stand, and what is the short-term outlook?
Nitrosamine impurities in Sartan drug products by GC-MS/MS
This application demonstrates a reliable GC–MS/MS method for analysis of nitrosamine drug products including the three impurities NDMA, NDEA, and NDBA listed by US FDA.
The Most Cost-Effective Makeup Gas for GC
Historically, helium has been used as a makeup or carrier gas. Learn about the disadvantages of helium and why so many laboratories are switching to nitrogen gas for GC.
