Increase Productivity for Dioxin and Furan Analysis with Rtx-Dioxin2 GC Columns
The cyano columns typically used for confirmational analysis of dioxin and furan congeners have low heat tolerance, resulting in long run times and high phase bleed that can limit sensitivity and shorten column lifetime. Rtx-Dioxin2 columns are stable up to 340 °C and provide isomer specificity for both 2,3,7,8-TCDD and 2,3,7,8-TCDF, allowing faster, more accurate analysis.

How Long Are Cannabinoids Stable in Working Standards?
You’ve prepared your calibration standards perfectly, but do you know how stable the cannabinoids are once you’ve opened the ampuls and diluted the standards? We tested this over 30 days using a mixture of 16 neutral and acidic cannabinoids prepared in range of solvents and stored under different conditions (-20 to 25 °C). Read on to see our results.
13-Minute, Comprehensive, Direct HPLC Analysis of Amino Acids in Plasma
This LC-MS/MS method demonstrated that 45 amino acids could be simultaneously measured in plasma—without derivatization—using a Raptor Polar X column. Acceptable accuracy, precision, and linearity results were obtained in a fast, 13-minute run, making this approach suitable for high-throughput labs.
