Since CL is a highly sensitive technique for detecting oxidative deterioration, it may be possible to establish the cause. Please feel free to contact us.

Since the oxidative deterioration in the very early stage can be seen compared to other methods, the development period can be shortened.

CL can also be used for acceptance inspection of raw materials and quality inspection of finished products.

It is possible. It can be evaluated even with a shorter accelerated deterioration time than usual.

By comparing and measuring the current material and the newly studied material, it is possible to measure and evaluate which is oxidatively deteriorated and which is easier to oxidize.

It is possible. CL can be evaluated at the early stage of peroxide formation, while other measurement methods detect late deterioration (final products and changes in molecular weight).

We have a track record of quantifying blood phospholipid peroxide, which is also an index of oxidative stress, and measuring cancer cells, skin and hair.

It is possible to see the difference in luminescent species and to elucidate the mechanism of oxidative deterioration.

When it becomes a molded product, it is important to evaluate the variation in which the part that deteriorates quickly accelerates the deterioration of the surroundings and affects the product life.

Please see some of them as application notes on this website.

It is possible. In the case of a thin film, it may warp during heating, so the sample may be held down with a glass plate or the like during the measurement.

It is possible. Pellets have different particle sizes, but weigh them together.

Basically, any material containing organic substances can be measured.

It is possible. In the case of oil, it can measure even about 100 μL.

It will be the size that fits in the sample dish. There are two types of dishes (φ50 mm x 10 mm and φ20 mm x 5 mm), and the larger the sample, the larger the amount of light emitted.

Set the gas type and flow rate → Set the measurement temperature → After reaching the set temperature, Insert the sample → Start the measurement.

If you do not want to cause oxidative deterioration during measurement, use an inert gas (nitrogen or argon), and if you want to accelerate oxidative deterioration, use an active gas (air, oxygen).

It will be about 50-150 ml / min.

There is no light source. This device detects and measures the Ultra weak light generated by the oxidation reaction .

It is possible. However, if the amount of light emitted is small, it may be measured above the melting point.

If it is below the melting point, it is not necessary to consider the phase change, viscosity change, and activation energy change point during measurement, which facilitates data interpretation.

The CLA-FS type has a spectroscopic function. If the amount of light emitted is large and the amount of light emitted remains the same for several minutes, spectrum measurement can be performed.

Since heat is applied, it is basically a destructive test.

Since CLA-IMG produces an image; you can see where light is emitted from the defective part.

We have equipment at the Sendai head office, Tokyo branch, and Kyoto lab, so it is possible if you visit us. However, imaging measurement is available only at the Sendai head office.

Since this method is a comparative one, for example, prepare a new product and a deteriorated product, or a product with a different deterioration time or anti-oxidant type.

When oxidized, there are many peroxides, so the amount of light emitted also increases.

Yes. Especially as antioxidants oxidize earlier than the base resin, they will emit luminescence first.

Separate peaks observed during the temperature rise result from differing peroxide decomposition temperatures, i.e. peroxides derived from the base resin and from the additive both emitting luminescence.

With CL, it takes time, but it is possible to measure even below the melting point. In addition, the CLA-IMG can measure multiple samples at the same time.

We provide the measurement data and since the data is saved in a csv file the results can also be presented graphically.

There is no maintenance fee (excluding consumables).

We recommend maintenance (overhaul) every 2 to 3 years.

Since our technique is extremely sensitive, measurements may be affected by light if fluorescent lighting or similar impacts on the sample. We recommend locating away from direct sunlight or any fluorescent devices.
