Product Overview:

The U.S. EPA TO-14/15 methods for determining VOCs in ambient air involve collecting air samples using SUMMA canisters, followed by analysis using GC technology. The methods provide guidelines for purging and verifying sampling canisters by measuring the residual VOC concentration after purging. Therefore, thorough and correct cleaning of sampling canisters before use is very important. The 960 series fully automatic sampling canister cleaning system allows automatic or programmed cycles of evacuation, filling, baking (100°C), and other operations to fully automatically clean sampling canisters, with humidified gas filling to ensure cleaning effectiveness. After purging, the canisters are ensured to be free of VOCs and dry, with vacuum reaching below 50mTorr.

Product Features:

• The system is available in split type and oven type; the split type can clean 4 × 6L or 15L SUMMA canisters simultaneously, while the integrated type can clean 4 × 6L or 2 × 15L SUMMA canisters simultaneously
• The system uses a built-in vacuum scroll pump instead of conventional primary and high vacuum pumps, making the instrument smaller in size, achieving vacuum below 50mTorr, and providing an unloaded flow rate of 100L/min
• The split type uses DC heating belts, with each DC heating belt having a heating power of 250W; the oven type has a heating power of 1000W, with fast and efficient heating
• All pipeline connections in the system are made of 316L stainless steel or PTFE material and undergo special treatment to effectively reduce adsorption
• The system uses microcomputer control, with the entire cleaning process completed automatically. A buzzer prompts completion of cleaning for user convenience
• The system uses high-precision absolute pressure sensors and vacuum sensors to monitor the internal pressure of the sampling canister, ensuring more accurate and reliable measurement and guaranteeing the purging effect
