DXI

Question 1

Red

Answer 1

Not ready, indicates either that system has stopped, or that initialization is in progress.

Question 2

Amber, steady

Answer 2

supplies required, one or more system supply are low or waste containers are almost full. The system will continue to process samples and schedule new tests.

Question 3

Amber, blinking

Answer 3

Supplies required, one or more system supply are out, or an area requires attention. the system will not schedule new test, but will complete tests in progress.

Question 4

Green

Answer 4

Running, system is processing tests or performing a maintenance routine.

Question 5

Blue

Answer 5

Ready, no processing operations are in progress, but the system is ready to begin processing.

Question 6

What occurs during Reagent addition

Answer 6

when a sample is in process, the reaction vessels is moved by robotic module to one of the reagent carriages, where a dedicated reagent pipettor transfers the required volume of sample into another vessels. The robotic module moves the RV to the incubator where it remains for a period of time.

Question 7

What occurs during the incubation period?

Answer 7

During incubation period paramagnetic particles from the reagents bind with analyte from the sample.

Question 8

What occurs during sample washing

Answer 8

once sample is incubated, the RV is moved to the wash carousel to begin final processing. As the wash carousel rotates, the RB moves through a 3 wash stations. In each wash, a dispense probe adds wash buffer to the RV

Question 9

What is the purpose fo the magnets in sample washing

Answer 9

magnets then draws the paramagnetic particles out of suspension, and pull them to the side of the RB

Question 10

What is the purpose of the aspirate probe

Answer 10

Aspirate probe removes the wash buffer, along with the unbound analytes.

Question 11

After 3 complete wash, RV is moved to the substrate probe. The purpose of the substrate probe

Answer 11

Dispense chemiluminescent substrate into the RV.
