Solid Phase Extraction(SPE)


Solid Phase Extraction Cartridges


Over the last twenty years, SPE has become the most powerful technique prior to analytical chromatography for the cleanup, purification, and concentration of samples from various matrices, including urine, blood, water, beverages, soil, and animal tissue. Solid phase extraction is a form of digital (step-wise) chromatography designed to extract, partition, and/or adsorb one or more components from a liquid phase (sample) onto stationary phase (sorbent or resin). SPE extends a chromatographic system’s lifetime, improves qualitative and quantitative analysis.


Benefifits of SPE

●Switch sample matrices to form more compatible with chromatographic analyses

●Concentrate analytes for increased sensitivity

●Remove interferences to simplify chromatography and improve quantitation

●Protect the analytical column from contaminants

 Common SPE Applications

●Pharmaceutical compounds and metabolites in biological fluids.

● Drugs of abuse in biological fluids.

●Environmental pollutants in drinking and wastewater.

●Pesticides and antibiotics in food/agricultural matrices. 

● Desalting of proteins and peptides.

● Fractionation of lipids.

● Water and fat soluble vitamins.

How to Collect Laboratory Waste Liquid Safely?

Image
In the field of chromatographic analysis, we often use HPLC, UPLC, flow injection and other instruments with mobile phase, which will produce a variety of hazardous waste liquid. How to collect waste liquid in a reasonable way is very important to ensure laboratory safety and personnel health. In order to solve this problem, Welch has launched a series of products about safety collection in laboratory as following. Connect-type safety collection device This device can be connected with HPLC, UPLC, flow injection and other mobile phase instruments to directly discharge the hazardous waste liquid generated during analysis to a sealed container. The special feature is that the organic steam filter can remove the pressure inside the container and filter the harmful volatiles. Different types of liquid level indicators are provided inside the container to remind the analyst to deal with the waste liquid in time. The standard version of this device includes one 20L certifi...
