Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a large group of nearly 15,000 synthetic compounds characterized by a fluorinated alkyl chain. The US Environmental Protection Agency (EPA) has been pursuing the reduction of PFAS emissions since 2004. As legacy PFAS were phased out, a new generation of compounds known as “emerging PFAS” were introduced as a replacement. Engineered to have shorter half-lives and faster bioelimination, emerging PFAS have nonetheless raised concerns about toxicity and environmental impact. Several methods exist for monitoring PFAS in water and soil, generally variations on official methods developed by EPA and ASTM International. No official methods exist for air monitoring yet, but adaptations of EPA air collection methods and European method CEN/TS ...

PFAS is a hot topic in the field of water analysis, with many of the testing labs gearing up to regulated 47+ compounds. This analysis can be tricky as there are many potential sources of contamination and losses. This presentation will include: 1. Direct LC-MS/MS water analysis 2. Approaches for water sample pre-treatment 3. Identifying sources of contamination 4. Method for the analysis of volatile PFAS in air

Event Overview This presentation includes an introduction to column selection and analysis examples, which are basic information necessary for gas chromatography. This webinar is suitable for chemical analysts in all fields using GC, such as chemical industry, environment, food, universities, and research laboratories. Key Learning Objectives ・ Expand your basis knowledge about gas chromatography ・ How to choose GC Column and get the best results ・ Learn about the applications

We provide a step-by-step guide on cleaning and maintaining HPLC columns for reliable results.

The GF1010 Digital Gas Flow meter is a portable handheld flow meter for gas chromatography systems.

MonoSpin is a GL Science`s original product for sample pre-treatment with centrifuge. MonoSpin enables concentration and purification of trace level samples like biological samples without any need for dehydration.

This video goes over sampling and solvent extraction using our MonoTrap gas sampler.

In this video we will introduce our recommended HPLC column washing method on normal phase mode.

In this video, we will introduce our recommended HPLC column washing method.

This video is part of a series that discusses HPLC reproducibility issues between columns. In this video, we will focus on the effects of the pH in a mobile phase.

This video is part of a series that discusses HPLC reproducibility issues between columns. In this video, we will focus on low robustness conditions when developing an application.

HPLC is a crucial technique for separating and analyzing complex mixtures into individual components. At its core is the column hardware and, in this video, we'll be breaking down its fundamental role and structure.

LD239 provides the most sensitive Helium leak detection available in an inexpensive, compact, easily charged (via USB), and easy-to-use configuration.

Quickly detect volatile sulfur compounds – the primary components of halitosis: hydrogen sulfide, methyl mercaptan, and dimethyl sulfide – using OralChroma's highly sensitive semiconductor detector and integrated column for efficient sample gas separation.

This video will help you understand what an HPLC guard column is, how to choose and install it.

This video discusses HPLC column problems caused by the quality of the mobile phase, focusing on organic solvents and water for HPLC.

Air Sampler for PFAS(FM4) is a new Low Volume Air Sampler which you can analyze PFAS in the particle and gas in one sampling. You can achieve comprehensive analysis in one sampling because each stage of it has optimized material and configuration for each target substance.

Proper installation of a capillary column is a fundamental yet critical step in constructing a gas chromatography (GC) setup for effective analysis. Discover how to accomplish this in our step-by-step instructional video!

This video introduces HPLC column troubleshooting related to column equilibration

Combine high precision flow and ease of use. The UI-22 HPLC pump uses a linear driver mechanism in which the plunger moves in line with the motor’s axis. Because aspirated air can be easily discharged, and with the seal suffering almost no wear, tiny leaks from the seal are eliminated, which means that even highly volatile solvents can be efficiently pumped.

Introducing our new HPLC Column factory in Japan where we produce our InertSustain and Inertsil HPLC Columns.
