Note: This procedure is only valid at the time of printing. The control version can be found on the Meraux Refinery intranet. Completed Date:Prepared By:Approved By: Micro-Distillation of Process Samples by ISL PMD-110 1Place volatile samples in ice bath to chill prior to analysis. 2Power on the PMD-110 from main switch on rear panel just above power cord. 3Press any key to bring display to the START menu. NOTE: If analyzer already on, access the START menu by pressing (back key) located to left of key on front panel. 4Check and empty the condenser waste beaker if level is too full. NOTE: Testing cannot be started without the waste beaker in position due to a safety micro-switch. 5Press the PRODUCT button. 6Select the sample type from list by navigating the highlighted bar with the arrow pad on keyboard. 7Press OK button. 8Press the SMPL ID button and input the alphanumeric sample ID; press OK button. 9(Optional Step) Press OPER button and select user running test with arrow pad; press OK. 10Into a clean, dry distillation flask add about 4 – 8 chips of small grain pumice stone. 11Fill plastic 10 ml syringe with sample; invert syringe and push plunger to 10 ml mark ensuring any air bubbles are removed

The control version can be found on the Meraux Refinery intranet. Completed Date:Prepared By:Approved By: Micro-Distillation of Process Samples by ISL PMD-110 (continued) 12Insert the syringe nozzle into distillation flask (while orienting the side arm of the flask upward) and slowly dispense sample into flask. NOTE: If sample is dispensed too quickly, spillage will occur which will alter result of the test. 13Life plastic protection shield up and away from the heating compartment. 14 Attach distillation flask to measuring head assembly ensuring flask is fully seated inside the black rubber lip seal (a click is heard when properly seated). 15Ensure spring loaded push rod for heating element is in the lower position. NOTE: Inspect o-ring on measuring head attachment for any cuts or wear – replace if needed. 16 Insert glass side arm tube of flask to condenser tube gasket opening, then gently press in the spring, clip as you attach measuring head (missing verbiage that wasn’t able to view on scanned documents). 17Press the spring loaded push rod for the heating elements to raise it to the upper position against flask bottom. 18Lower plastic protection shield over the heating compartment. 19Press START NOW button to begin test. NOTE: Once distillation is complete, result is automatically calculated and displayed on screen. A print-out of the results will be automatically initiated. 20An audible alarm will sound at end of test – press button with picture of bell ( ) to display alarm condition; i.e. “end of test”. 21Press button for ACQUIT to silence alarm. NOTE: At end of test, the heater compartment cooling fan will run for five minutes. 22Lift plastic protection shield and press spring loaded push rod to lower flask heating element. 23Once distillation flask has cooled, press spring clip of the measuring head and gently pull it from the connection. 24Remove distillation flask from measuring head and place in flask holding device. 25 Immediately wipe liquid condensate from measuring head with a lint free tissue – wipe both temperature probes and the upper hole around the black sealing ring. 26Return the measuring head to the holder. 27Clean distillation flask first with toluene and then with acetone. 28Return distillation flask to holder in the inverted position to allow it to drain. 29If any flasks are heavily coated with carbon residue, place them in muffle furnace to clean.
