Kori-xr

Explore a robust, cryogen-free TD–GC–MS solution for monitoring 30 volatile fluorinated compounds (VFCs) in stationary sources. The UNITY– CIA Advantage-xr combined with Kori-xr water management allows for accordance with the canister-based method OTM-50 whilst meeting compliance with QC. Discover the advantages of this sensitive and efficient solution and how it can support you in monitoring PFAS destruction and environmental safety.

In this application note, Markes highlights the robust, reproducible analysis of trace VOCs and sulfur-containing compounds using the Air Server-Kori-UNITY-xr™ coupled to a GC–MS system.

This poster describes the successful application of Markes’ innovative on- and offline method coupled with Agilent’s powerful GC–MSD, which combines sampling and analysis in a single run with a cycle time under one hour, ensuring consistent hourly monitoring of all compounds, even remotely.

This scientific poster describes the successful application of Markes' innovative on- and offline solutions, combining all compounds of interest into a single run with a cycle time under one hour, ensuring consistent hourly monitoring for all compounds, even remotely.

This application note describes cryogen-free sampling and analysis of PAMS ozone precursors and TO-15 air toxics in high-humidity environments, in compliance with new Chinese air-monitoring regulations. The use of Markes’ groundbreaking Dry-Focus3 preconcentration and water management technology results in excellent chromatographic peak shape at 100% humidity, whilst maintaining sample-to-sample cycle times below 60 minutes.

This is a comprehensive guide to monitoring chemicals in the environment and the workplace using thermal desorption. It describes how thermal desorption can be used in air and water monitoring applications including detection of ‘air toxics’, mapping of environmental pollutants and assessing underground contamination. In each case, the guide directs you towards relevant application notes which describe the methods mentioned in detail. The guide also describes relevant analytical and sampling techniques and outlines the advantages of using thermal desorption for environmental monitoring.

This application note describes the GC–MS analysis of humidified canister ‘air toxics’ samples at various relative humidities, using cryogen-free systems for thermal desorption preconcentration. Detection of 65 target compounds, ranging in volatility from propene to naphthalene, is demonstrated with excellent peak shape and performance well within the criteria set out in US EPA Method TO-15, including method detection limits as low as 4 pptv.

This application note describes how thermal desorption (TD) with GC–MS can be used to analyse trace-levels of volatile and very volatile organic compounds (VOCs and VVOCs) in ambient air. The article compares options for adapting these methods for high humidity samples, including use of the new Kori-xrTM system. The article highlights the benefits of Kori-xr, including enhanced recovery of low-boiling and polar VOCs and its sensitivity to important polar compounds ethanol and acetone
