Reagent Module
Disposable module contains all reagents and a waste container.
The reagent module is equipped with an electronic chip which contains
encoded information which is automatically read by the analyzer upon
installation of the reagent module. This information includes:
l
calibrant concentrations for pH, PCO
2
, PO
2
, Hct, Na
+
, K
+
, Ca
++
,
and Cl
-
;
l
current reagent module serial number and installation date;
l
analyzer serial number that the reagent module was first installed
on;
l
reagent volume % remaining with the number of days remaining
before calibrants expire.
Prior to installation, a reagent module must be stored at room tem-
perature for a minimum of four hours. When the center of the indica-
tor on the back of the reagent module becomes dark, the module has
been exposed to excessive heat and must not be used.
After initial installation, the reagent module is functional for a limited
number of days (see reagent module insert sheet). After each calibra-
tion, the reagent module % and days remaining are printed. When
the reagent module has 0% remaining, RGNT MODULE EMPTY
is displayed. If the reagent module has exceeded the allowable usage
period, RGNT MODULE EXPIRED is displayed. Both of
these conditions require reagent module replacement.
Valve Module
Selects reagents from the reagent module, preheats and directs them
through the probe.
Sensor Module
Thermostated housing for the electrodes. The sampler containing the
probe is attached. A bubble detector above the electrodes detects fluid
or air in the fluid path.
