Analytical Chemistry in Pharmaceuticals and Medicine Manufacturing

Maximizing Soy Milk Quality Attributes through Particle Size Analysis

In this note, the final result of soy milk processing is evaluated with particle size analysis. Particle size results give a quantitative measure of the soy milk that can be used to ensure consistent production and product quality.

Measuring and controlling the particle size distribution of cement is important both in order to achieve the desired product performance and to control manufacturing costs. Laser diffraction is the more popular method to determine the particle size distribution as the technique is quick, easy, reproducible, and provides a complete picture of the full size distribution.

$Milk compounds characterization by optical spectroscopies and laser diffraction$

In the food industry, the compounds characterization is a critical step to ensure the quality of the products or to provide information to customers which can be sensitive to allergies. In this application note, we showed how optical spectroscopies and laser diffraction can help for food compounds characterization, especially on a specific product, i.e. milks.

Spectroscopic Methods for Sunscreens Characterization

This Application Note outlines three different kinds of spectroscopic tools being used for the characterization of sunscreens, and discusses the obtained results. These include Fluorescence spectroscopy for photoactivity, Particle Size analysis for composition and Raman microscopy for formulation investigation.
