App Notes

This brief presents a quick and simple method for the determination of fipronil and fipronil sulfone in eggs using an in-house modified QuEChERS acetonitrile extraction protocol.

MS analysis of antibodies at the protein and peptide levels is critical during development and production of biopharmaceuticals.

Over the last few years, mass spectrometry based proteomics has evolved into an extremely powerful enterprise.

Peptide identification and sequencing strategies by mass spectrometry have been very well-developed during the last 25 years after the soft ionization techniques have been introduced.

The FFNSC Library can be an excellent support and applied in essential oil characterization, food aroma profile analysis, determination of fragrances in non- food matrix (e-liquids, cosmetics).

Completely automated elution, eluate filtration, and determination of 2,4-DNPH derivatives of airborne aldehydes and ketones by HPLC-DAD and LC-MS/MS is presented.

This application looks at how the low cost 200 Series GC can be used to monitor for contamination.

This application looks at how the low cost 200 Series GC can be used to monitor compounds for product consistancy.

This Application Note describes validation of a cryogen-free thermal desorption (TD)–GC–MS system for on-line monitoring of an extended range of very volatile species in ambient air.
