3. Biochemical Test Functions and Operation

3.1 Working Principle

The principle of analyzer is based on Lambert-Beer Law.

3.2 Operation

Switch on the equipment, screen shows as below

Click on the screen and enter the selection interface, then select to enter different menu function,

which can perform edition, setting and testing, etc.

Select “Biochemical” to enter its main interface

Select keys you need

Test: To select the biochemical items to do sample test, after testing, the equipment will

show the test results and print it automatically

Edit: To add, modify, delete and print biochemical items.

Result: Result print, print, delete, QC management, QC statistics and printing general

BS Series Multitest Analyzer

report, etc.

Wash: The shortcut key for cleaning, aspiration volume is 1.5ml per keystroke, used to

clean flow cell.

Feed: Used for printer to load papers, pass papers and cut papers

Pump: Calibration for Peristaltic pump aspiration volume

Gain: AD Auto Zero to confirm whether the instrument is in the regular test status.

Filter: Measure and adjust each filter’s AD value, blank value and absorbance

Setup: Show cuvette temperature; set filter number, cuvette diameter, language, aspiration

mode, sleep mode; Hospital and instrument model title Settings; time format and

date/time Settings; screen brightness settings, etc.

3.3 Parameters settings

3.3.1 Temperature display Settings

Use to choose Temperature, click main menu to save. This function can only provide

the confirmation on whether temperature is right or not. When testing sample, the

temperature will be shifted according to the test program. Input the password and then input

calibration temperature (for professionals only). Password: 123456.

Attention:

Filter wheel, cuvette, aspiration mode, language setting, screen brightness settings, the

password are all 123456.

3.3.2 Pump calibration

BS Series Multitest Analyzer

The default values of the instrument is that 3000ul aspiration sample volume corresponds

to 20000 motor steps. When the aspiration volume is not correct, adjusting is necessary.

Enter into the calibrate interface, input pump calibrate volume, then pour corresponding

distilled water into the tube, insert pipette into water, press PUSH to aspirate. After the

distilled water was sucked done. Press PUSH again, the instrument will display motor step

and exit pump calibration to save step. If the aspiration volume is still not right, repeat the

above operation or input moter steps directly.

3.4 Instrument operation key process

3.4.1 Instrument preheating

Connect to the power and turn on the switch, the instrument should be preheated in

10-30 mins.

3.4.2 Pipeline Washing

Clean the flow cell before using it, enter into the main interface, insert the pipette into

distilled water, and then press wash to start washing, last 5-10 times.

Attention:

●Pay attention to use environmental dustproof, moisture proof, and installation air

conditioning is better, environment temperature in 18-25 ° C is the best working

temperature.

● When external power is not stable, instruments must connect regulated power supply

●Instruments in the process of operation shall not open the cover, so as not to cause

damage to equipment or operator

●Leakage and electrostatic prevention, the instrument should be in good grounding. Line

power socket must have a reliable grounding line to guarantee in a steady state and

security

●After work, wash the instrument 3 times at least immediately to keep the cuvette and

pipeline from liquid waste.

●After finish the testing, the used should be collected and disposed according to the

medical waste.

●The waste pipe end should not be dipped into the waste to avoid poor drainage.

●Use qualified reagent within the period of validity.

BS Series Multitest Analyzer

3.4.3 AD Auto Zero

Select AD Auto Zero from the main menu, the screen will show as below:

Press Push to aspirate distilled water and click Continue

And then click read

When AD auto zero, put the aspiration pipe into distilled water, press push, then the

instrument begin to zero. The interface will show Gain coverage, AD value and offset

value, if the value is out of range, there will be alarm reminding.

Attention:

AD auto zero is that the instrument is based on water to measure the initial light

intensity of different wavelength. The gain coverage, AD value and offset value

are calculated together to obtain absorbance. This step is very important; users

should do this step at each starting the instrument.

AD auto zero for flow cell need more distilled water, it is recommended that the

aspiration pipe should insert into distilled water to ensure no bubble when AD

auto zero.

It is also available to use cuvette for AD auto zero; the distilled water in the

cuvette should reach more than 10mm away from the bottom of the cuvette.

4. Specific Proteins Test Function and Operation

4.1 Principle

Specific proteins test is based on the light scattering principle. When immune complex which

consists of specific proteins meet incident ray in detection System, the intensity of scattered

light at 90 degrees is directly proportional to amount and size of immune complex within certain

limits.

4.2 Operation

Attention:

Choose scattered light when testing specific proteins, put macro cuvettes or micro cuvettes

with adaptors into test pots to proceed. However, the flowing cuvette is not available for

this test. In addition, there should be light-shield upon cuvettes to ensure stability of

detection signal.

Go to the main menu, choose “Specific protein”

The Device starts specific protein testing mode. Selected and set different function keys

according to need. Keys reference is made to “Biochemical” and “Coagulation” menu.

5. Device Maintenance

5.1 Daily Maintenance

Daily maintenance is mainly on washing the flowing cuvette, keep it clean. Before testing,

10 times washing are necessary. After each test, wash 4-5 times is essential. If there are

bubbles in flowing cuvette, you may draw ethanol to soak and flush firstly, then wash it by

BS Series Multitest Analyzer

distilled water. When all tests done, please use distilled water flush.

5.2 Weekly Maintenance

Weekly maintenance is on washing the flowing cuvette by detergent. Keeps detergent

resting in cuvette 5-10 min before draining. Then flush it repeatedly by distilled water

Recommended detergent:

1. 20% sodium hypochlorite solution

2. 95% absolute ethanol

3. Dedicated Detergent for chemistry analyzer

5.3 Monthly Maintenance

Daily maintenance is mainly about cleaning dust and stains on the casing, correct sample

absorption amount of peristaltic pump.

5.4 Other Maintenance Items

Generally using coagulation cuvette and micro detector cuvette to perform “Coagulation”

and “Specific Protein”. Cuvettes should be properly kept away from scratching. Cuvettes

and magnetic rods should be original parts of Sinnowa to avoid obtaining wrong results.

6. Troubleshooting

This chapter explains all kind of malfunctions, which often happen in the routine operations.

Besides, it analyzes the related reasons about malfunctions and supplies some methods against

the malfunctions.

Warnings:

●You must turn off the analyzer, cut off the power, and then remove the power plug from the

socket. The repair work must be taken by SINNOWA professional trained men.

●The analyzer must use suited power supply and voltage. Or else, the damage which is

caused against this order is out of SINNOWA’s responsibility.

Caution:

●Analysis of samples may give incorrect test results in the case of instrument malfunction. If

there is a fault detected in the sample, be sure to troubleshoot before use.

●Sample, quality control samples, calibration samples, wasted liquid and so on have potential

biochemistry risk. The operator must comply with the laboratory regulations about the

safety operator to wear personal protective device (like: laboratory protective clothing,

gloves etc.), and accordance with local government regulations to dispose the waste

materials generated by the instrument detection.
