General Information<br />
When the calibration is complete the flow cell drains as the sample flow<br />
returns. The flow cell volume returns to the measurement level. After<br />
allowing approximately 30 minutes for concentrated calibration solution to<br />
be flushed from the system, the Orion <strong>2110XP</strong> can begin sample<br />
measurement again.<br />
In addition to Double-Known Addition (DKA), the Orion <strong>2110XP</strong> also<br />
allows the user the ability to perform an offline calibration.<br />
Offline Calibration<br />
The offline calibration feature of the Orion <strong>2110XP</strong> allows the user to<br />
adjust the monitor to values determined by alternate methods used in their<br />
laboratory such as elemental spectroscopy and ion chromatography.<br />
The offline calibration is essentially a one-point calibration. To perform an<br />
offline calibration, a sample is taken from the bypass of the instrument; the<br />
sample concentration value is stored in memory; the sample is analyzed by<br />
an alternate method of choice; the previously stored reading is adjusted to<br />
the lab method result; and the instrument is then returned to the analysis<br />
mode. The term “offline calibration” refers only to the fact that a sample<br />
from Orion <strong>2110XP</strong> bypass is taken “offline” for laboratory analysis; in<br />
fact, no downtime is experienced during the procedure and the instrument<br />
remains online throughout.<br />
