App Notes

Monoclonal antibodies (MAbs) are immunological active proteins, which bind specifically to certain cells or proteins. This will stimulate the immune system to attack those targets.

The term “forensic” drug refers mainly to chemical or plant-derived substances that affect psychological, behavioral, or physical functions.

In this application note we present the use of a simple sample extraction and dispersive solid phase extraction (dSPE) cleanup procedure.

A new automated thermal desorption (TD)-GC/MS method is presented for combined determination of formaldehyde, other airborne carbonyls and VOCs in material emission testing.

This application note describes the fully automated extraction of carboxy-THC from urine.

Steviol glycosides, the main sweetening compounds in Stevia rebaudiana are used as natural sugar substitutes.

An inert sample pathway is critical for accurately quantifying low levels of active sample that are common in today’s analytical applications.

This study demonstrates the high performance of a dynamic headspace sampler with TD–GC–TOF MS analysis for investigating the complex aroma profiles from hops.

The characterization of intact monoclonal antibodies by mass spectrometry is challenging due to the size and complexity of the molecules.

Here we demonstrate the detection and quantitation of several biogenic amines that have been shown to affect beer flavor.
