You `specifics!ly asked about availability of refurbished HlnlMonltoro and about the oompasltion of the plastlo begs. Present deliveries are from 4-6 weeks but should Improve to 1-2 weeks by January 1990. The plaacio bag is made from polyethylene and should be used for only short term storage of the MlnlHonttor. To minimise contamination of the bags and therefore the monitor* the bag may be stored In a desleeator <not the one used for the via! kits) with "protection charcoal,- Copies of the current price list and the operating procedure are enclosed for you to distribute at the upcoming meeting.

We have had massive da I ays in processing orders for mew or refurbished monitors and must apologize for them. Deliveries should bs improving shortly* The density of the charcoal has changed again and the new recommended charge will be printed on all bottles shipped after September 5, 1990. If you use the premeasured vial, you needn't make any changes in your procedure. The adsorptlon-deeorption -properties are Identical to previous batches. The new charcoal has a narrower mesh range of 20-36 mesh, fewer snail particles, and will appear to have a somewhat larger size than the 80*40 mesh, To keep you up to date ve have Included with this letteri 1.

Cool the sample to -20 oc On e freezer) and add 5 irtL af cold (dry ice) carbon disulfide slowly so that no charcoal or solvent spatter from the vial. Standards are prepared (n the same way except the carbon dlaulfida is added to an empty vial (use no charcoal to prepare standards). Natei The desorption apparatus (Cat. No* 0-24) in figure 1 lo particularly convenient for desorption because it allows the carbon disulfide to be measured at room temperature. 2. Recap the vial immediately after adding the carbon disulfide and allow to stand 80 minutes* 3. Shake the vial at 10 and 20 minutes after solvent addition. 4. Inject S uL into a gas chromatograph equipped with a flame lonizati.cn detector* The column used should be ehosen to separate possible Interfering species that ocour In the environment being sampivdi however* a 6 ft 1/S In, Chromosorb 102 (Johns Mansvllle) or a 20 ft. 1/8 in* FFAP column are oomnonly used.

No. 0*21 (or 0-22 In vials) or equivalent should be used. Carbon disulfide (reagent or speotrosoopic grade) should be as pure as possible to speed analysis time. calibration of the monitor The monitor should be calibrated before use If not purchased calibrated. Expose the device to a known concentration (10 ppm) of vinyl chloride for a given period of time (2 hr). This can be done conveniently by placing the monitor In an aluminum or glass chamber (Cat. No. 0-25> with the calibration gas moving through the chamber at about l L per minute per monitor being exposed Permeation tubee Are probably the most accurate source of vinyl chloride standards, while compressed gas standards are more convenient. The calibration constant can be calculated from the equation! k*t w # To facilitate rapid addition and removal of charcoal a vibrator (engraver) should be touched to the badge clip. ** The same sampling and desorption procedures can be used for Freon12.
