- HILIC
- Hydrophilic-interaction liquid chromatography. Polar stationary phase, high-organic mobile phase. Retains polar analytes that reverse phase cannot hold.
- High-resolution mass spectrometry
- Sufficient resolving power to distinguish species differing by a small fraction of a dalton. Required to exclude 1 and 2 Da alternatives.
- Host cell protein
- Protein from the expression organism carried through purification. A required specification for recombinant products and reported on none in this index.

- Oxygen in the gas space above the product. Correlates with sulfoxide content and is essentially never measured.
- Hygroscopic
- Readily absorbing atmospheric moisture. Proline-rich short peptides and NAD+ are the worst offenders in this index.
