A heat shield is provided to reduce the risk of getting burned while the ATIS is in use. The temperature of the heat shield will be approximately half of the set block temperature. - Page 4 The ATIS Components • Operation Manual 1. Block Heater 2. Injector Heater Block 3. Gas Purifier 4.

- Page 7 Note: The thermometer port is dual tapered and will accept both a normal thermometer, or a smaller diameter digital thermometer. The ATIS is now completely assembled. Your set-up should look like the picture to the right.
- Page 8 For odd size tubes use the Luer/Hose-Barb Adapter included. The pictures below illustrate some examples. NOTE: While using the ATIS, the temperature of the adsorbent tube will be close to the ambient temperature of your lab. However if the adsorbent tube is attached to the thumbwheel for a long period, the heat from the injector block will transfer to the attached adsorbent tube.

Page 9: Setting The Temperature
Setting the Flow Rate (Carrier Gas) Insert the type of adsorbent tube you plan to use in the thumbwheel of the ATIS, and gently tighten the thumbwheel. With the gas supply on, attach a flow meter to the opposite end of the adsorbent tube. -

To accurately quantify the concentration of a sample acquired with an adsorbent tube, the analytical system must first be calibrated. The ATIS simplifies this task. Below are a few starting parameters, some experimentation may be needed to optimize the conditions for your application. - Page 11 By volatizing the compounds with the ATIS, this allows you to use the contents of the bag immediately without having to let it equilibrate overnight.

To use the extraction glassware, simply remove the injection glassware from the injector heater block and reinstall the fittings as described in the assembly instruction of injection glassware. See Appendix 2: ATIS Glassware Configurations for additional information. In most extraction applications, the block... -

Then after sampling, reweigh the tube. If the difference is greater than 2 milligrams you may want to remove the moisture prior to analysis. Attach the tube to the ATIS and allow 0.5 to 1 Liter of the carrier gas to pass through the tube. Reweigh the tube. The adsorbent tube can be considered dry when it is within 1.0mg of the weight of the tube prior to sampling. -
