Rejecting data (Outliers)

Your data may not fit your pet idea, or even the generally accepted scientific theory, but that does not they are wrong.

TIC/TOC – measuring carbon

Meausring the carbon content of soils, sediments and rocks is a key measurement in geochemistry and other related sciences.

Kelly Vere: A voice for technicians

For the last 2 years, Kelly Vere has been talking about technicians to every important person she can find, representing us [technicians] at the Science Council.

BET surface area

BET is one of the few methods available for surface area measurement and has the advantage of being able to give a measure of porosity.

Calibration standard preparation using volumetric flasks.

Preparation of calibration standards

Calibration standards are key to the analytical process as they are used to create the calibration curve. Better the calibration standards the better calibration curves and so the better the results.

It’s calibration time!

For most measurements in analytical chemistry some form of calibration curve is required. The better the calibration the more accuracy and precise are the results that you can achieve.
