Reagent Container Types; Sampling And Analysis Of Photometric Tests; Sample Aspiration; Sample Tray - Siemens ADVIA 1800 Operator's Manual

The reagent pumps (RP1 and RP2) withdraw reagent from the reagent trays, and also
discharge the reagent into the RRV cuvettes. The reagent probes execute both actions.
During both actions, the reagent pump valves (RPEV1-1, RPEV2-1, RPEV1-2, and
RPEV2-2) are closed.
After the reagent is aspirated, the probes move to the wash ports, where their outsides are
washed. RPEV2-1 and RPEV2-2 (wash cup valves for RPP1 and RPP2, respectively) are
open during this process. This allows water to flow over the outside of the probes.
After the reagent is dispensed, the probes move back to the wash ports, where their insides
are washed. RPEV1-1 and RPEV1-2 (valves for RTT1 and RTT2, respectively) open,
allowing the sample and reagent wash pump (SRWP) to send degassed water through the
probes' insides.
After the wash, the water drains down the wash port.

Reagent container types

Place reagent containers defined at the Reagent Container Settings window in the reagent
trays. The trays can hold 20-mL, 40-mL, or 70-mL wedge-shaped containers.
At this window, you also specify the reagent type (R1 or R2) for each reagent container.
Barcode labels on reagent containers have the test name, expiration date, lot number, and
container ID number. You can initiate a barcode scan at the Reagent Inventory window.

Sampling and analysis of photometric tests

Sample aspiration

Sample tray

The sample tray holds patient samples, controls, calibrators, and diluents for measurement.
The tray rotates to move the samples to the aspiration position.
The sample tray has two sections:
•
STT (outer section): Used for general samples and reference samples for multipoint
calibrations. It has two rows, each with 42 positions (total 84). You can place serum or
urine samples into each position.
A barcode reader identifies samples in the STT. It can interpret barcode formats Code
39, Interleaved 2 of 5, Codabar, Code 128, and NW7.
•
CTT (inner section): Used for calibrators, controls, and special purpose diluents. It has
two rows. The outer row has 34 positions and the inner row has 27 positions (total 61).
The CTT is water-cooled.
