Claver Scope The method is designed basically for measuring vinylchloride (VCM) in atmospheres in and around operations involving VCM. With minor changes the procedure can be applied to measurement of VCM in liquids. Detectability of VCM by this method is <0.1 ppm (Vol/Vol) . Repeatability is estimated to be 10% of the value. Summary Air samples are collected in 16 oz. narrow mouth bottles. The bottles are closed with serum caps to make syringe sampling possible. One ml gas samples are analyzed by gas chromatography utilizing a Porapak Q column. Method I. Equipment A. Perkin-Elmer model 900 gas chromatograph, or equivalent. (Flame ionization detector necessary.) B. 10 pi and 1 ml GC syringes. C. Standard laboratory glassware. II Reagents A. Vinylchloride (VCM) B. Tetrahvdrofuran (THF) III Procedure A. Arrange gas chromatograph as follows: 1. Column: 7.5 ft, 1/8" OD, Porapak Q 100/120 mesh 2. Carrier Gas: N- @ 75 ml/min 3. Column Temp.: I30C 4. Injector Temp.: 170C 5. Sample Size: 5 pi 6. Retention Time for VCM: 2.25 min RSV 0017195 2 B* Calibration 1. VCM standard solutions* a* Place about 40 ml of THF in a 50 ml volumetric flask and weigh. b. Chill (dry ice) this flask and a quantity of VCM to -20C or lower. c. Transfer, by pipette or graduated cylinder, about 1 ml VCM to the volumetric flask containing THF. d. Mix VCM and THF well by gentle swirling and allow to warm to room temperature. e. Reweigh the flask and contents and add THF to volumetric mark. Note: 1 g VCM/50 ml = 21000 ppm (wt./vol) f. Dilute quantities of solution from e to give about 50, 100 and 200 ppm VCM in THF. g. Introduce, by syringe, 5 ul of each of the standards in turn into the gas chromatograph. h. Convert weight of VCM in each 5 pi sample into volume VCM and plot vs. peak height in standard units such as mm Weight to volume conversion is done at standard pressure and temperature for purposes of this measurement. Micrograms divided by 2.79 x 10 ^ gives microliters 62.5 g (mole weight) _ 22.4 1 (mole volume) 70 Then for samples, microliters per ml = ppm VCM in air samples 1 ml in size. C. Sample Runs 1. Wet the plunger of a 1 ml GC syringe with a small quantity of silicone stopcock grease. 2. With a syringe thus prepared carefully withdraw 1 ml of the gas sample from septum capped bottle and inject into gas chromatograph. 3. Read VCM peak height and read ppm VCM from prepared calibration graph. RSV 0017196 3 IV* Precision A. Because of: 1. Volatility of VCM 2* Use of standard conditions for converting weight of VCM to volume, and 3. Use of syringe for sampling the precision of this method is not high. Indications are the precision is 10% or better. V. Safety VCM and THF are toxic materials. Both must be handled in a forced draft fume hood. Transport of VCM to experimental area should be done in a suitabl metal pressure container.

Fox - Texas City, Texas e : October 28, 1974 SUftJtCT BttMNCK * Vinyl Chloride Survey at Customer Plant cc G. A. Danner VC. L. Gilmore J. G. Trafton TO : L. David Press MIC - St. Louis Si'* As per your request, air sampling for personnel exposure to vinyl chloride was carried out at a customer's plant who uses our EVC latex in carpet manufacture. The customer. Coronet Industries, is located at Dalton, Georgia. Air sampling was conducted with the aid of the Sipin personal sample pumps which draw a measured amount of air through a small tube con taining charcoal. The analytical method is dependent on the adsorption of vinyl chloride from air by the activated charcoal followed by desorp tion of the vinyl chloride from the charcoal by carbon disulfide. The CS2 is then chromatographed to determine the amount of vinyl chloride present. The range of the method is 0-1000 mol. ppm of vinyl chloride in air with an accuracy of approximately 5% of the amount present. Two air sampling procedures were followed: 1) Three of the Coronet personnel were assigned to wear the sample pumps for approximately six hours. 2) Ten to twenty-eight minute air samples were collected by me at selected operations and/or locations. The enclosed tables tabulate the results. JEF:wy Attachments RSV 0017218 17 number f#i/ OVEN %!<> FP0t* S pf>F>DE& r.ft 7" ots L i!
