From Clear to Pure: Chemical and Color Analysis in the Petrochemical Industry

Chemical analysis is an intricate part of our everyday lives. From the water we drink to the food we eat to the fuel we put into our car, nearly everything we consume has undergone some form of chemical analysis before use. Although it’s likely not something we consider as we go about our daily activities, it’s a vital aspect of the production process for many things and something we all rely upon for quality assurance.

Petrochemical manufacturers know that chemical analysis is one of the most important steps in the monitoring of chemical compounds in the petroleum refining process. It is also one of the most unique and difficult processes to quantify and analyze. The ability to detect color changes is an important step in the process for identifying contaminants and impurities. With the right technology, the challenges of chemical analysis can be met.

Colorimetric Scores: Making Sure Your Tomatoes Make the Grade

The bright red color of the tomato can tell us a lot about quality and nutrition.

Color terminology has been changing; what we once called red is now referred to as magenta. Well, you know how the song goes: “you say tomato; I saw tomahto.” However, when it comes to color there is only one standard by which to abide.

Colorimetric scores are an important component for quantifying color in order to create the measurements needed to relate product quality to a grading scale. These scores have been developed through extensive research and analysis of tomato products at various stages of production to ensure color consistency and maturity. Various colorimetric methods and spectrophotometers have been used to revolutionize the tomato industry and lead to higher standards in all tomato-based products. Continue reading

Numerous studies have recently been conducted regarding color psychology. Color can tell us a lot about who we are, how we are feeling, and the choices we make. Why do people prefer their lemonade pink? And why is that “little pill” blue? Well, it is certainly not by accident. As human beings, there is a direct correlation between our senses and color. Color psychology not only impacts our internal thought processes, it also has a great deal of influence on consumerism — especially when it comes to pharmaceuticals. All major drug corporations know that color is one of the most important ingredients in prescription medications. That is why they depend on the highest levels of color technology and spectrophotometry in order to maintain consistency and accuracy in their product. Continue reading

Colorimetry has been used in a variety of scientific studies to create specific color standards and visual comparisons. The standards and comparisons within this field can be of great value when evaluating color and consistently repeating data. Test results in colorimetrics through the use of spectrophotometers can give us a wealth of information about the choices we make that are dependent on color, especially those involving the foods we eat.
