Sample prep

How you prepare your sample really depends on what kind of balance you’re using. Precision balances have larger capacities and less fine readabilities. They’re ideal for weighing larger samples that do not require weights measured past the thousandths. Analytical balances offer lower capacities with finer readabilities. Moisture analysers require different sample preparation than regular weighing balances.

Maintaining quality and integrity of samples is of the utmost importance. How you handle and store your sample depends heavily on the type you’re working with. Many samples have specific temperature requirements. Organic material like DNA or bacteria should be kept either refrigerated or frozen, while powders may tolerate ambient temperatures.

Your sample should be completely “pure,” without any disruptions or outliers. This guarantees that your sample represents the whole, reducing errors. Size reduction may involve taking parts from a whole to make the sample easier to weigh.

Vibrations, static, draughts, and temperatures in the environment will try their best to make your very sensitive balance go haywire. Draughts, luckily, are mitigated by the addition of draught shields over most analytical and semi-micro balances, as well as many precision balances.

The best way to keep thorough records is by using software, which automatically performs statistical analysis for multiple scales at once, not only keeping records but spinning them into workable data as well. Without proper sample preparation, your weighing results won’t give you the information you’re intending to get.
