A much discussed issue related to Near Infrared Analysis (NIR) is the necessity of sample preparation. Ground and unground samples of wheat were analyzed to determine how truly necessary it to homogenize samples before NIR analysis.

The quality of sample preparation often determines the quality of the results and the conclusions drawn from experiments.

The biggest challenge for weighing instruments is weighing small samples with reliable accuracy. Knowing the minimum weight of the instrument solves this issue.

Today’s laboratory environment is very different than it was several years ago. Advancements in science make everyday routines quicker and put a higher focus on accuracy and reproducibility

CEM has developed a method for the simultaneous and rapid preparation of vastly different food sample types for trace metal analysis.

The goal of homogenization is to process samples quickly and efficiently while maintaining the quality of the end product. A major factor in successful homogenization is the reproducibility of samples.

PW analytical balances provide users with an accurate and consistent tool for density determination of different materials.

A critical component of any sample preparation is making the sample homogeneous. However, when working with a large number of samples, this is often a time-consuming and labor-intensive task.

Homogenization seeks to create samples in which analytes of interest are dispersed uniformly throughout. Numerous technologies can achieve this, including pressure, mechanical (rotorstator or blade-type), and bead-beating.

Microwave digestion is the preparation method of choice for analyzing metals in complex mixtures. Food and environmental industries favor this technique, which is also applicable to testing materials, soil, agricultural waste products, engine oils, and biological samples.

Milling and grinding are ancient techniques that are working their way into high-tech markets.

Grant Instruments, an international supplier of precision sample preparation equipment, has recently added a General Purpose Centrifuge to their Grant-bio line of products.
