Rxi®-5Sil MS Columns: Assured Performance for Forensic ApplicationsRxi®-5Sil MS columns produce excellent results for a number of forensic applications. The versatile selectivity separates a wide variety of compounds, which lets you keep analyzing samples instead of changing columns between methods. |
 |
Optimized Volatiles Analysis Ensures Fast VOC SeparationsAnalytical conditions for GC analysis of volatile organic compounds have been optimized to ensure good resolution of critical pairs, while maximizing sample throughput. Rxi®-624Sil MS columns are shown to outperform other 624s. |
 |
Rxi®-624Sil MS Columns - Exceptionally Inert, Low Bleed Columns for Volatiles AnalysisAnalyze volatile compounds and polar analytes with greater confidence using Rxi®-624Sil MS columns. Optimized selectivity, higher inertness, and lower bleed result in reliable separations and accurate, trace-level determinations. Includes environmental and pharmaceutical applications. |

Combined Determination of 1,4-Dioxane and Nitrosamine Contaminants in Drinking Water Using SPE and CST-LVSI GC-MSTypically, 1,4-dioxane and nitrosamines are analyzed in drinking water following separate extraction and analysis procedures, such as Methods 521 and 522. However, here we present a combined method that uses large volume splitless injection and GC-MS (SIM) to meet low part-per-trillion detection limits for these compounds in a fraction of the time required when running separate methods. |

A Fast, Simple FET Headspace GC-FID Technique for Detemining Residual Solvents in Cannabis ConcentratesAs the cannabis industry expands, demand is increasing for analysis of residual solvents in cannabis concentrates in order to protect consumer safety. This application note details a simple, fast, accurate test for common residual solvents using full evaporation technique headspace GC-FID and an Rxi®-624Sil MS column. |
 |
A Preliminary FET Headspace GC-FID Method for Comprehensive Tepene Profiling in CannabisThis application note describes an FET-HS-GC-FID method that was developed in hops for the analysis of terpenes in cannabis. Good chromatographic separation allowed quantification of critical compounds across the volatility range, including α-pinene, β-myrcene, α-humulene, β-caryophyllene, and caryophyllene oxide. |
 |
Rxi®-1301Sil MS GC ColumnsThe new Rxi®-1301Sil MS column is ideal for the analysis of multiple compound classes across a range of polarities and volatilities. With its cyano-based selectivity and high thermal stability, it is the best 1301-type column for robust MS analyses. |
 |
