Adding multiple detectors to a GPC unit enables the system to meet the needs of today’s advanced polymer industry.
The use of ultrapure water in RNA research using in situ hybridization ensures contamination-free, reliable results.
Chirality plays a critical role in drug efficacy because enantiomers may have vastly different biological, pharmacological and toxicological properties. Smaller particles and the addition of MS detection help speed chiral analysis time and accelerate method development.
As helium becomes a rarer resource for gas chromatography practitioners, hydrogen is filling the void as a viable alternative that can offer superior results. Chromatographers are increasingly choosing to switch to hydrogen, a gas easily and inexpensively produced safely through an on-site generator.
Gas chromatography (GC) remains one of the most important and widely used analytical testing techniques performed today across a number of industries. Harvesting the power of application-specific phases, as opposed to general purpose columns, allows both performance and productivity gains.
Ion chromatography (IC) is an established procedure that allows researchers to separate ions and polar molecules based upon their charge. New IC technologies have increased the resolution and throughput of these instruments, allowing new applications to be serviced.
FTIR has emerged as a viable alternative to gas chromatography for the qualitative and quantitative analysis of gases. Qualification and quantitation are performed from the wave numbers of the characteristic peaks and peak intensities of the measured gas.
If there was a method for packing material manufacturers to specify shape characteristics and for column manufacturers to inspect incoming materials against those specifications, manufacturing HPLC columns would become more predictable, less costly and exhibit consistent performance. Recent advancements in image analysis could provide the answer.
