Low Vol Samplers
croyce:
I am trying to find out some best practices for folks doing environmental air sampling on Low Vol samplers.
I am out doing some environmental sampling on a site to corroborate the site owners analysis results. The sight owner and myself are using Low Vols. We have different brand low vols HiQs vs F&Js but both are being run for the same flowrate (2 CFM) over the same period of time(7 Days). I'm running a 2" glass fiber filter while the site is running a 47 mm glass fiber (not a big difference there). The site does use an older rotormeter for it's flow rate adjustment while I use a digital system. Also the site field calibrates flow rate upon every change out but doesn't not get an annual calibration. I do not do field verifications but calibrate annually with verifications on a quarterly basis. In the past it has been my practice to verify the sampler is still running on a daily or every other day basis during a long run such as a 7 day period. The facility does not have this practice. They will only touch the sampler upon initiating the sample and when pulling it 7 days later.
What do you do? Do you touch the sampler daily to verify that it hasn't shutdown or do you let it run for 7 days?
Do you operate a digital module that logs power outages or do you have an analog system?
How often do you calibrate or do verifications of flowrate?
Thank you for any help.
SloGlo:
did knot check environmental a/s pumps after turning on.
used old school flow gauge witch lacked any outage monitoring.
calibrations were done annually. flow verification consisted of recording flow rate at start/stop.

It does not sound like he is obligated to follow any of their procedures, rather he is doing an independent investigation of their procedures.
