When using the pressurized sampling option with the AS950 sampler, can the sample source be located below or above the AS950 sampler?
AS950 and pressurized sampling
Yes, the pressurized sample line can be located above or below the elevation of the sampler. Unlike the 900MAX that had different options for being above or below the sampling point, the AS950 pressurized sampling option can be used for both installations. The motorized ball valve (number 6 in the figure below) must be located below the sampler and as close to the sampler as possible, allowing the line to purge adequately.
