Best and Worst Organic Solvents to Use in LC

There are several critical characteristics to take into consideration when choosing the appropriate organic solvent to use in liquid chromatography. For example, high viscosity solvents may produce backpressures that are too high for the HPLC system used.

Technical Tip: Early Eluting Peak Shape

Depending on method conditions, early eluting compounds are apt to have poor peak shapes. Within are some steps that can be implemented to help minimize any distortions to early eluting peaks in gas chromatography.

Poor Sample Recovery? You May Be Over-Drying

For most reversed-phase solid phase extraction applications using a silica-based SPE media, cartridges are initially conditioned using an organic solvent such as methanol, followed by rinsing with water or a buffer.

Is Water Safe To Inject In Gas Chromatography?

In the first GC columns, gas chromatography phases were simply coated onto the column. This was mostly the case with packed columns, but also the same with the very first capillary columns. Injecting water onto these phases dissolved the phase and caused the phase to elute from the columns.

Technical Tip: Principle HPLC Conditions for LC/MS

High-performance (or pressure) liquid chromatography, more commonly known as HPLC, can be a useful tool to assist in the improvement or simplicity of mass spectral detection and analysis.
