|
| The SRI
Automatic Calibration System (ACS) allows for automatic, unattended recalibration
when using an SRI GC equipped with the TO-14 Air Concentrator for ambient
air analysis. |
|
|
| Under
control of the PeakSimple software included with the GC, the ACS can make
dilutions of the customer-supplied standard gas and Zero Air at ratios of
10,000 to 1. For example, if the standard EPC on the TO-14 GC is set to
50psi, a 100ppm standard gas flows through the restrictor at a rate of 100
milliliters per minute; the Zero Air flows at a rate of 1,000 milliliters
per minute. This produces a 10ppm diluted gas, which is sampled into the
TO-14 Air Concentrator by the vacuum pump (supplied with the TO-14 Air Concentrator). |
 |
| By manipulating
both the EPC pressure and time, the 100ppm standard can be diluted over
a 10,000 to 1 concentration. For example, let's say you've decided to use
300 seconds as the length of time the vacuum pump |
