Q1 - What is the maximum temperature requested? A1 - A maximum temperature is not specified. The interior temperature needs to be high enough to prevent condensation of water vapor, maintain the sample in a vapor state and ensure transmission of the following target compounds at greater than 75% efficiency. Target compounds include Bis(2-chloroethyl)sulfide (HD); Dichloro-(2-chlorovinyl) arsine (L); Bis(2-chloroethyl)amine (HN1); Tris(2-chloroethyl) amine (HN3); O-Ethyl-S-(2-diisoproylaminoethyl)methyl phosphonothiolate (VX); Ethyl N,N dimethyl phosphoramidocyanidate (GA Tabun); Isopropyl methylphosphonofluoridate (GB Sarin); Pinacolyl methylphosphonofluoridate (GD Soman); Cyclohexyl methyl phosphonofluoridate (GF Cyclosarin); Carbonic Dichloride (CG Phosgene); Trichloronitromethane (PS-Cloropicrin); Cyanogen chloride (CK-Cyanogen chloride); Trichloromethane (CF-Chloroform) Q2 - Should the design include a temperature controller? A2 - The lines shall self-regulate for temperature. Q3 - A temperature sensor. A3 - See answer to Q2. Q4 - Is this for indoor or outdoor use? A4 - The line must be suitable for use in outdoor environments ranging from 0 to 120 degrees F. Q5 - What chemical agents and at what level are they present in the samples? A5 - Chemical agents are listed in the response to Q1. Chemical agent standards are prepared to a predetermined concentration so that when 4 microliters (µL) are injected, the spike mass (in nanograms, ng) per sample volume equal 1.0 VSL. For example, 4µL of HD prepared at a concentration of 1.8 ng/µL yields a spike mass of 7.2 ng. The sample volume we use for HD for this standard .concentration is 2.4 Liters. 7.2 nanograms of HD in 2.4 Liters of air yields a concentration of 3 ng/L. 3 ng/L = 0.003 mg/m3 = 1.0 VSL HD. The industrial compounds CG, CK, PS and Chloroform are diluted into a 1 Liter Tedlar bag to reflect a concentration of 1.0 PEL (permissible exposure limit). The following agent concentrations are used by the CBC EML: • HD, HN-1, HN-3, L - 1.8 ng/µL • VX - 0.006 ng/µL • GA, GB - 0.06 ng/µL • GD, GF - 0.03 ng/µL Q6 - What media (material) are you going to use the transfer lines for A6 - Transfer lines will be used to transport air vapor samples to monitoring equipment (MINICAMS), which monitor airborne chemical vapor concentrations. Q7 - Are there any requirement for saturation levels? A7 - Typical concentration levels are 400-500 vapor screening level (VSL). A maximum saturation level would be approximately 1,000 short-term exposure limit (STEL). Q8 - Is it self regulated or temperature controller used? A8 - See answer to Q2. Q9 - If temperature controller is used, what type of sensor is required? A9 - See answer to Q2. Q10 - Is there a max weight required for the product? A10 - The lines cannot weigh more than 50 lbs.
