Thermal desorption releases suitable organic compounds from sorbent media and transfers them to a GC system for TD-GC-MS analysis. Selection depends on analytes, sample matrix, humidity, throughput and sampling mode. A portable sampling pump collects air onto a TD tube; a tube conditioner prepares suitable tubes for use.<\/p>\n

| Single-channel air sampler<\/th>\n | Battery operated; manufacturer-rated runtime 20 hours at 300 mL\/min; low-flow mode 0\u201399 mL\/min, high-flow mode 100\u2013600 mL\/min; flow accuracy \u00b15%; 540 g.<\/td>\n<\/tr>\n |
| Tube conditioners<\/th>\n | Single- or six-tube versions; maximum 400 \u00b0C; for 6 mm \u00d7 4.5 in and 1\/4 in \u00d7 3.5 in tubes; other sizes require suitable adapters.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n Standard equipment and options differ between models. In particular, the 7550 requires a concentrator, while the 7550S and 7550S Pro have an integrated focusing trap. Tube dimensions and sorbents must be matched to the selected configuration.<\/p>\n Manufacturer information<\/h3>\nCDS 9300<\/a> \u00b7 CDS 9305<\/a> \u00b7 CDS 9350<\/a> \u00b7 CDS 7550S<\/a> \u00b7 CDS 7550S Pro<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" Product-group reference: CDS-TD-001<\/p>\n CDS systems for TD-GC-MS and air sampling, from individual sorbent tubes to automated sequences and continuous air monitoring.
