Thermo Fisher Scientific has developed a reproducible and accurate ion chromatography (IC) method for determining monochloroacetic acid (MCAA) in carbocisteine drug substance and two carbocisteine drug products, thus enabling efficient quality control of the carbocisteine manufacturing process.

Thermo Fisher Scientific has released a new 58-page compendium for its solid-core HPLC columns (Thermo ScientificTM AccucoreTM HPLC columns) titled, Solid Core Technical Compendium.

Thermo Fisher Scientific has developed an ion chromatography (IC)-based method for the determination of ammonia in adenosine that can easily meet the sensitivity requirements in the U.S. Pharmacopeia (USP) adenosine monograph.

Most HPLC analyses employ some form of sample preparation, especially with low-concentration analytes in complex mixtures.

Gas chromatography (GC) is a common technique used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. GC is typically used for separating the different components of a mixture, improving the purity of a particular substance, or identifying a particular compound. GC is a ubiquitous technique, and the various GC instruments available are designed to achieve every requirement of the technique.

"More laboratories are opting to generate their own gas, on-site," said John Speranza, Vice President of Global Sales at Proton OnSite.  "For Gas Chromatographers (GC) who are struggling to source inexpensive helium gas, hydrogen is the superior carrier gas alternative..."

Helium is commonly used as the makeup gas for flame ionization detection in gas chromatography;
however, dramatic increases in cost and limited availability in recent years have led many chromatographers to use nitrogen in its place.

For all its maturity and secure establishment in chemical analysis, predicting the future of gas chromatography is an exercise in uncertainty.

As regulators have redefined environmental methods for low-abundance analytes, and demanded the analysis of more analytes, column manufacturers have done well to provide greater sensitivity and selectivity.

The webinar will feature a panel of experts representing leading vendors in the field, who will provide their perspectives on what a user should consider when deciding which system is right for their lab and its applications. Each panelist will give a brief presentation to highlight the recent improvements in columns, sample preparation, instrumentation and analysis software for GC and LC systems

Thermo Fisher Scientific has developed a method for the fast determination of PCDD/Fs in sediments, soils, bottom and fly ash (as incineration by-products) using gas chromatography-tandem mass spectrometry (GC-MS/MS).
