What is a Spectrophotometer?

Detecting a chemical compound without a spectrophotometer never being easy. That why every chemistry lab is equipped with this analytical device. Spectrophotometer works by separating the spectral of light and measure its component intensity. Since some chemicals absorb light thus the intensity of the adsorption can be measured by using a spectrophotometer and its concentration could be quantified. Light Light is some sort of electromagnetic radiation emitted from its sources. It could be light from the candle, lamp, sunlight reflected… Read More »What is a Spectrophotometer?

Sustainable and Alternative Chemical Sources

Concern on oil depletion and global warming has shifted us to sustainable alternative energy such as solar and wind energy. But we could not stop just yet to produce chemicals from petroleum oil. Chemicals are essential building blocks for us to make fabric, plastic ware, container, paint, solvents, shoes, carpet, medicine, flavor, fragrances, additives, and much more. There is a various option for energy sources, but there are no sustainable alternative chemical sources just yet. Without chemicals, our lifestyle would… Read More »Sustainable and Alternative Chemical Sources

Free software to Draw Chemical Structures and Chemical Reaction Schemes

Drawing chemical structure with online tools is very easy and quick. Most of them actually developed for finding chemical properties from its chemical structure. But it allows us to download the chemical structures as an image. Thus, we can use the image for scientific reports, presentations and etc. However, this tool offers very limited functionalities. In fact, we cannot save our work if we want to continue drawing the structure at a later date. Here I shared with you the… Read More »Free software to Draw Chemical Structures and Chemical Reaction Schemes
