Gas standards (cylinders) used for calibration of our continuous moni toring system are prepared from certified vinyl chloride purchased from our suppliers. Before use each standard is analyzed in our laboratory by comparison to a calibration curve freshly prepared from three gas mixture standards (5 , 10, and 50 ppm vinyl chloride in nitrogen cylinders, certified by the gas manufacturer). 5. Continuous monitor sampling point locations in relation to floor level and equipment in vinyl chloride service are illustrated in the enclosed drawings. 6. A series of three (3) GC columns are used in our Model 1200 VFA continuous monitor: a. 20% Igepal CO-880 on Chromosorb P AW DMCS (60/80 mesh) 1/8 in. O.D. SS x 18 in. b.
