Other non-carbon sorbents

Quartz beads A range of other non-carbon sorbents are available for specialised applications, including:

Silanised glass wool – Recommended in place of quartz wool in sorbent tubes and focusing (cold) traps when analysing extremely labile compounds, although prone to degrading at high temperatures (>275°C).

Unsilanised glass wool – With rigorous conditioning, can be used in sorbent tubes where inertness is not an issue.

Quartz wool – Often used as the first ‘sorbent’ in a multi-bed sorbent tube when very high-boiling compounds are being sampled.

Quartz beads – Completely inert, and used primarily in focusing (cold) traps when monitoring high-boiling, chemically active compounds; can be used in sorbent tubes in place of quartz wool.
