Use of the Intrada Amino Acid column along with tandem mass spectrometry allows for separation and detection of all 20 standard amino acids in under 20 minutes. This column enables the separation of isobaric amino acids such as leucine and isoleucine.

The Intrada Amino Acid column is used to separate amino acids present within soy sauce

The Intrada Amino Acid column separates all 20 amino acids in under 15 minutes without requiring tedious pre or post labeling methods

The Intrada Amino Acid column sucessfully separates 55 amino acids and related compounds without requiring derivatization

The Scherzo SS-C18 column is effectively able to retain and resolve polar dipeptides.

The Scherzo family columns can separate this glycopeptide with varying retention. The Scherzo SW-C18 has the least retention, followed by the Scherzo SM-C18, followed by the Scherzo SS-C18 which has the most retention.

The Scherzo SM-C18 and SW-C18 columns can separate this glycopeptide with varying retention. The Scherzo SM-C18 has less retention while the Scherzo SW-C18 has more retention.

The Scherzo SS-C18 column retains and separates glutamic acid and GABA better than a conventional C18 column
