Chromatography is a fundamental analytical technique used to separate mixtures into their individual components. It is widely used in the chemical and pharmaceutical industries and crucial for various stages of drug development, production, and quality control. How chromatography works 1. The sample mixture to be separated is dissolved in a fluid (liquid or gas) called the … Continued
Read moreWe often get the question: How can I be sure to get the correct Hazen color value if calibration standards only go up to 500 PCU and my solution’s color is well above that? Well, absorbance is a function of concentration and thus correlates to color, according to Beer Lamberts law: Absorbance ≃ concentration As … Continued

Read moreOptical Density (OD) is a measurement used in biotech to quantify DNA, RNA, and proteins. But what is it exactly? In simple terms, OD is the amount of light absorbed at a specific wavelength divided by the distance the light travels through the sample (optical pathlength or OPL) in centimeters. It represents the absorption you … Continued
Read moreDid you know? During the early stages of shampoo in Europe, English hair stylists boiled shaved soap in water and added herbs to give the hair shine and fragrance. Commercially made shampoo was available from the turn of the 20th century👴 Modern shampoos offer cleansing, conditioning, and some even have medicinal benefits. Evaluating these products involves various quality control tests, including turbidity measurement 🧴 Turbidity, … Continued
Read moreDiscover how the Kemtrak TC007 turbidity analyzer revolutionizes crystallization process monitoring. In this video we demonstrate the power of real-time turbidity measurement in optimizing crystallization processes. By precisely pinpointing the nucleation point, the TC007 ensures improved yields, reduced solvent consumption and enhanced batch-to-batch consistency. Through a sodium acetate crystallization, you’ll see how the TC007, paired … Continued
Read moreWhat is it? Ultrafiltration is a type of membrane filtration where pressure gradients force liquids through a semipermeable membrane. The membrane’s pores are small enough to retain macromolecules like proteins and polysaccharides, while allowing smaller molecules and solvents to pass through ⚗ How it works: · Membrane Structure: ultrafiltration membranes have pore sizes ranging from 1 … Continued
