Filters for instruments
Filter disks are used in tube receivers to prevent flow path blockages. Instrument filters should be checked and replaced regularly as part of a routine maintenance plan. Split tubes can be used multiple times, but should be routinely replaced – Markes recommends at least every 12 months. Split filter tubes should never be desorbed.

Overview
Markes’ thermal desorbers offer quantitation of the widest possible concentration range, through flexible splitting of both inlet and outlet flows. Split flows can be collected onto a re-collection tube for storage or repeat analysis, but when not required, the split can also be collected onto a tube packed with charcoal for subsequent disposal.
Split filter tubes are available for three types of TD system:
- On-line systems use a glass industry-standard size tube
- Tube-based systems use a stainless steel industry-standard size tube
- 4½″ DAAMS tube-based systems use a stainless steel 4½″ long × 6 mm o.d. tube
