Infrared Oil Analyzer Overview

How Infrared Spectroscopy Works

An infared oil analyzer checks what is in oils and lubricants. The analyzer has a few main parts. These are an infrared light, a sample holder like an ATR crystal, a detector, and a data system. You put the oil sample on the analyzer. The infrared light goes through or bounces off the oil. Chemical bonds in the oil take in certain colors of the light. This makes a special spectrum for each oil sample. The spectrum is like a fingerprint. It shows what is in the oil and if anything has changed.

The analyzer gathers this spectrum and sends it to the data system. You see the results as a graph with high and low points. Each high point matches a certain chemical bond in the oil. This way, you can find problems like contamination or changes in the oil. You can use this method to check for total oil and grease (TOG), fats, oils, and grease (FOG), and total petroleum hydrocarbons (TPH). These things help you watch oil quality and keep machines working well.

FTIR Technology in Oil Analysis

FTIR means Fourier Transform Infrared. People use FTIR in oil analysis because it is quick, correct, and does not hurt the sample. FTIR uses a special way to get the spectrum. This makes it easier to see small changes in oils and lubricants. You do not need to do much to get the sample ready. This saves time and helps stop mistakes.

With FTIR, you can check many things about the oil at once. You can see if the oil has mixed with other things or if it is breaking down. FTIR can find even tiny amounts of other stuff, sometimes as little as 5%. You get a full chemical picture from just one test. This makes FTIR great for checking quality and watching oil condition. The spectrum from FTIR gives you clear answers about the oil. You can make fast choices. FTIR also saves money because you use fewer chemicals and need less training. You can trust FTIR to give good results every time you use your infared oil analyzer for infrared analysis.

Using the Infrared Oil Analyzer

Preparing for Oil Analysis

You need to get ready before you start oil testing. Good preparation helps you get the best results. Start by making sure your infrared oil analyzer is clean and working. Check that the ATR crystal or sample holder is free from old oil or dust. Use a lint-free cloth or the cleaning tool that comes with your analyzer.

Follow these steps to prepare your oil sample for analysis:

1. Take a clean dropper or pipette.

2. Place a single drop of the oil sample directly onto the ATR crystal. You do not need to dilute the oil or add chemicals.

3. Avoid using old methods like pressing oil into pellets or making thin films between salt plates. These are not needed for FTIR-ATR analysis.

4. Use the oil sample as it is. This saves you time and lowers the chance of mistakes.

5. If you work with used engine oils, make sure the sample is well mixed before you take a drop.

Tip: Always use gloves when handling oil samples. This keeps your hands clean and stops you from adding contaminants to the oil.

Collecting Oil Samples

You must collect oil samples with care. The way you collect the sample affects your analysis and the data you get. Use clean bottles or vials made for oil testing. Never use containers that held other oils or chemicals.

Here are some best practices for collecting oil samples:

• Clean all tools and containers before use.

• Avoid touching the inside of the bottle or the sample with your hands.

• Label each sample with the date, machine name, and type of oil.

• Store the oil sample in a cool, dry place until you are ready for analysis.

• For used oil, take the sample from the middle of the oil stream, not from the top or bottom. This gives you a true picture of the oil condition.

Note: Poor cleaning, dirty tools, or bad storage can add contaminants to your oil sample. This can change your results and make your oil analysis program less reliable.

Running the Analysis

Now you are ready to run the analysis. Turn on your infrared oil analyzer and let it warm up if needed. Follow the steps on the screen or in the manual.

1. Place the oil sample on the ATR crystal or in the sample holder.

2. Close the cover if your analyzer has one.

3. Start the analysis by pressing the correct button or using the touchscreen.

4. Wait for the analyzer to scan the oil. This usually takes only a few minutes.

5. The analyzer will show a spectrum on the screen. This is your data.

If you test used engine oils, repeat the process for each sample. Clean the ATR crystal between samples to avoid mixing oils.

Tip: Always check that the analyzer is calibrated before testing. Calibration helps you get accurate results every time.

Interpreting Results

After the analysis, you will see a graph or spectrum. This shows how the oil sample absorbs infrared light. Each peak on the graph matches a chemical bond in the oil. You can use this data to find out if the oil has changed or if it has picked up contaminants.

Look for these things in your results:

• Peaks that show water, fuel, or other contaminants in the oil.

• Changes in the base oil, like oxidation or breakdown.

• Signs of wear metals or additives in used engine oils.

Compare your results to past data from your oil analysis program. This helps you spot trends and make good choices about machine care. If you see big changes in the oil, you may need to change the oil or check the machine for problems.

Remember: Good data and careful analysis help you keep your machines safe and running well. Used oil analysis gives you early warnings about problems.

You can also export the analytical results to a computer or cloud system. This lets you track oil samples over time and share data with your team.
