  • In the sample extraction step during the gas chromatography mass spectrometric (GC-MS) analysis of free (FAA) and combined amino acids (CAA) in aerosol samples.
  • Preparation of tryptic digests from the standard protein samples and milk digests from milk samples.
  • Preparation of C60-aminopropylsilica.

Packaging

1, 4×2.5, 4, 4×4 L in glass bottle
