Step-by-step guide to use Roche 9180 electrolyte analyzer
This analyzer is one of the simplest and easiest to operate. Just like the Easylyte electrolyte analyzer, you operate the analyzer with a YEs and No keypad making it easy for even a student to use with less or no supervision.
Running a control
- Press No until QC/STD/DIALYSATE/URINE SAMPLE appears.
- Press Yes for QC Level 1 Sample? To be displayed and press Yes again.
- Press Yes again for Open Sample Door Introduce Sample to be displayed.
- Carefully whirl evenly to mix a Level 1 small glass tube that you took out of the ISETROL box.
- To discard any liquid, lightly tap the tube’s head with your fingernail.
- Gently remove the lid from the small glass tube
- Introduce sample appears when you open the cover of the probe
- Hold the tube containing the control under the probe to reach the bottom of the tube until Wipe Probe/Close Sample Door is displayed.
- Use a tissue to clean the probe gently
- Close the probing chamber.
- Wait for the results and compare the manufacturer’s results to that of the results you obtained.
- Press Yes when Store values in memory to save or press No to reject
- Values accepted will appear for a brief time followed by QC Level 2 Sample if you save
- Qc Level 1 will appear if the results are rejected by pressing No
- Press No until Ready is displayed
Testing a sample
- Be in your lab coat and gloves.
- Spin the sample to obtain the serum or plasma.
- Run the control and compare the manufacturer’s results to that of the results you obtained.
- Press Yes as an answer to the command Ready
- Raise the cover of the probe and introduce the sample will be displayed.
- Place the Eppendorf tube containing the serum under the probe making sure the probe touches the bottom of the tube for aspiration till you hear a beep and wipe probe/close sample door is displayed
- Wait for about 50 seconds for your results to appear.
- Press No and as Print Function Appears you press Yes.
- Press Yes again to answer Print Last Sample Report.
Performing Daily Maintenance
- Press the No key up until the DAILY MAINTENANCE message appears, then press Yes to choose.
- Press Yes to choose Perform Daily Cleaning
- Pour a small volume of the cleaning solution into a spotless container and place it under the probe for aspiration as directed by the prompt Open Sample Door Introduce Sample.
- Hold the cleaning solution underneath the probe until Wipe Probe/Close Sample Door is shown, then wipe the probe clean with cotton. Gently close the aspiration chamber.
- Pour a small volume of performing condition into a clean tube whiles the analyzer will display Thank You for a brief moment.
- Press Yes when Perform Daily Conditioning is displayed.
- Raise the door of the aspiration chamber and place the solution under the probe for aspiration when Open Sample Door Introduce Sample is displayed.
- Hold on to the conditioning solution beneath the probe until Wipe Probe/Close Sample Door and clean it with cotton. You then shut the door of the aspiration chamber.
- Press No when Remain in Daily Maintenance appears after Thank You is displayed for a short time.
- Automatic calibration will now commence. Check out the principle of the tissue processor.
Setting the date and time
- Press No, until the actual day is displayed.
- Press Yes and the cursor will move to the month.
- By keeping the NO key depressed, the analyzer will automatically scroll through the numbers, first slowly, then faster.
- Press No, until the actual new month is displayed. To accept this value, press YES.
- Press No, until the corrected year is displayed.
- Press Yes. Now, the corrected date will be displayed.
- Follow the same procedure to enter the current time.
- After entering the time, the analyzer will prompt OK?
- Press Yes if the date and time entered are correct.
Why is it important to set the correct date and time on the analyzer?
You will recall from the test procedure that I was able to save the test. This is done in order to retrieve test results that are misplaced. Since the date and time have been set you can easily obtain your results when you key in the ID of the patient. Check out the iris urine analyzer.
What is the principle of operation of the Roche 9180 electrolyte analyzer?
The principle of this machine is the Ion Selective Electrode technology.
In the Roche 9180 electrolyte analyzer, there are six separate electrodes: sodium, lithium, potassium, ionized calcium, chloride, and the reference electrode. The ion-selective membranes on each electrode interact with the appropriate ions in the sample under investigation in a certain way. This membrane acts as an ion exchanger, changing the membrane potential that is built up in the film between the sample and the membrane in response to the electrical charge of the ion. This is also similar to the smartlyte electrolyte analyzer.
The kind of electrolyte in the sample triggers a particular reaction in an ion-selective membrane. The membrane acts as an ion exchanger by adjusting its potential or measuring voltage in response to the ion’s electrical charge, which accumulates in the film between the sample and the membrane. The difference between the two potential readings on either side of the membrane is determined by a galvanic measuring chain inside the electrode. You can also read about the principle of the Gazelle HB Variant.
The reference electrode, the reference electrolyte, and the “open terminal” close the galvanic chain through the sample on one side. Near the opposite side are the membrane, inner electrolyte, and inner electrode. An electrochemical potential forms on the membrane of the active electrode due to the different ion concentrations between the inner electrolyte and the sample. The inner electrode transfers the potential to an amplifier’s input. Take a look out for VERASENSE Orthosensor for knee injury.
The second amplifier input as well as the ground are both linked to the reference electrode. Since the reference electrode is on the ground, signal processing can be done by magnifying the electrode potential. Then, using a calibration curve generated from two measured points of standard solutions with precisely known ion concentrations (two-point calibration), the measured voltage of the sample, and the Standard-A reference electrode, the ion concentration in the sample is measured and shown.
What is the price of the Roche 9180 electrolyte analyzer?
The prices of analyzers is affected by the shop you buy from, geographical location, delivery rate and money others. It can go for approximately $3,500.00 at the IndianMart.
The Roche 9180 electrolyte analyzer is known for its simplicity due to its Yes and No keypad. It is also known for giving accurate concentrations of electrolytes when reagents and the machine is in good working condition. There are other electrolyte analyzers I have termed as the best electrolyte analyzers you can also work with.
