App Notes

Gradient HPLC can be hyphenated with GPC/SEC in a fully automated setup to measure molar mass and chemical composition distribution of copolymers simultaneously with highest peak capacity.

Helium is well known as Helium that makes balloons and airships float and in its liquid form, Helium is used in a variety of applications including cooling for magnets in Magnetic Resonance Imaging (MRI) scanners, cooling infrared detectors, and as a superconductor coolant in the large hadron collider at CERN.

This application note present a simple yet rugged analytical procedure for direct analysis of 2- and 4-MI using hydrophilic interaction liquid chromatography (HILIC) and UV detection.

Nuts are considered nutrient dense foods and their consumption has been associated with reduced risk of coronary heart disease. The health benefits of nuts are partially attributable to their high content of unsaturated fatty acids.

Infrared spectroscopy can be used as an analytical measurement technique to identify the molecular constituents (chemical groups) of an extremely wide range of solid, liquid and gaseous sample types.

Laboratories that switch gas supply from helium to hydrogen can see a number of benefits including reduced overheads, faster throughput and even improved separations.

Hydrogen has long been considered as the best carrier gas for gas chromatography. In many cases hydrogen has become the carrier gas of choice since it results in fast analysis, high efficiency, reduced costs, and prolonged column life.

Here we show the reasons behind the helium shortage, what hydrogen offers the chromatographer and show how hydrogen can improve the separation of analytes in a complex mixture of compounds whilst improving the throughput of sample.

This application note describes the results of the ligation efficiency of manual library preparation versus automated library preparation.

This Application Note shows that BenchTOF time-of-flight mass spectrometers, coupled with GC, can provide a high-performance solution for the detection and quantitation of aroma compounds in wine extracts.
