There are several FTIR analysis sampling techniques that can be used to understand a material’s structure and identify the material, each with their own proficiency: Attenuated Total Reflectance –In ATR spectroscopy, an infrared beam is guided onto a dense and highly-refractive crystal at a very...
OPJ files can be up to 170 MB in size, but are often around 54 KB - 1 MB. The file type was created 10 years ago, but is still used today. The files contain the following words: CPYA 4. Files like these are about data, sample, plot, figure, ftir, time, results, origin, ...
With narcotic quantities making up such a small proportion of the total weight of the chemical that officials are trying to identify –almost down to trace quantities – the technical capabilities of Raman and FTIR are at the edge of effectiveness. A bag of white pills containing carf...

If you don't believe the myriad of chemists who have told you this, I invite you to learn chemistry, then take an FTIR of these liquids. Are you saying Heidi and her parents faked the whole thing since she was born? To what reason?
In previous articles, we wrote about the January 1905 discovery of the world’s largest gem-quality clear diamond, which was the “Cullinan” diamond, found in Pretoria, South Africa — a 3,106-carat diamond weighing 1.33 pounds. You can read about what happened to the Cullinan diamond below...
identification and quantification of plastics and microplastics in complex environmental matrices (such as wastewater and biosolids) and their changes over time. His research includes the use of modern potentiometric and spectroscopic tools (such as ToF-SIMS, micro-FTIR, XPS, EXAFS) to describe these...
The analysis can also be FTIR, NMR or another spectrographic or chromatographic technique when looking for a specific chemical. This procedure is used most frequently in the pharmaceutical industry to ensure that no cross-contamination occurs between drug production batches or that a batch of drugs ...
create strong brand preferences among the customers. Another important reason for Nike’s success was that they read the consumers mind perfectly. Nike does not sell “Nike air max” shoes, it sold a way of life, which is key to its success. 关键系数为耐克是他们能创造强的品牌特选在顾客之...
In order to insure accurate flash point results it is important that a representative sample be presented to the instrument. For various reasons, this is easier said than done. It is worth noting that the precautions here are equally true for any test (FTIR, gas chromatography, etc.) used ...
