Choosing the SLE correct elution solvent based on analyte properties produces the cleanest extracts with the highest recoveries.

This concept seems simple today, but traditional nitrogen evaporators haven’t been overhauled for many years. Even in our lab we were not able to store evaporation methods…until now!

It is easier to understand something when you know what the actual word means. A thermistor is a portmanteau (yes, sometimes I do pay attention to linguistics) of the words thermal and resistor. This ...

Phenolic compounds can be some of the most challenging compounds to extract from the compound lists in EPA Method 8270 and EPA Method 625.1. The recovery of these compounds suffer tremendously compare...

For anyone who processes samples in an EPA-regulated laboratory, you know that these methods can be very specific in some spots, and incredibly vague in others.

It is question and answer time and we are starting with TurboVap® evaporators and their use in an environmental lab. The TurboVap® evaporation system by design utilizes a patented gas vortex shearing ...

When working in a contract lab or any analytical testing lab, you may be prone to periods where it seems like there is never going to be a light at the end of the tunnel, as the samples just keep on c...

Have you ever tried a new-to-you technique, only to find yourself frustrated by the lack of results? Frustration that only seems to compound when you search for resources that may help you get started...

Historically, solid phase peptide synthesis has been conducted at room temperature, demanding long reaction times and often double coupling to ensure a quality crude peptide product. More recently how...

UV detection and fractionation is ubiquitous in flash chromatography. It is the default methodology used to detect and collect eluting compounds. Today’s flash chromatography systems offer UV-triggere...
