Air Contaminant in the Hycar-Polyacrylate Area
DAT6 THIS LETTER
August 19, 1976
Many materials were collected inyour recent Tenax tube sampling of the Hycar polyacrylate
area. Enclosed is a table from Bob Lattimer's report* describing the mass spectroscopic
analysis of the Tenax tubes.
-
It is clear that the Tenax sampling has shown us what to expect in this work room air. Mow we should conduct carbon tube sampling to measure the concentration of hazardous materials in the area. -
I recommend that you prepare carbon tube samplings in the following manner;
1. Sample areas, not men; 6 samples will be sufficient. 2. Use the small MSA or SKC carbon tubes 3. Sample at 50 cc/min and pump approximately 5 liters through the tubes. k. Record the necessary data to determine the actual volume of air sampled. 5. Cap and ship the tubes to Sue Kurtz at the Environmental Lab. 6. Include with the field samples a blank. 7. Prepare the blank by breaking the glass seals on a tube and then immediately
capping the tube. Store this tube with the field samplings after the samplings are complete.
In adddition to samp!ing with the carbon tube, please make several OVA measurements and record them. These OVA measurements will be helpful during the analysis.
If you have any questions about these findings or the proposed testing please call me.

3 An "X" indicates the component was found in the tube; *'?" indicates a questionable identification.
k Spectra for these compounds are virtually identical-
c As many as six C*-benzene isomers (MW13*) were observed. The most abundant isomer is probably diethyl.
^ May be due to Tenax GC decomposition.
