Double Beam Type Balance and Moisture Scales
BALANCE, Trip, Double-beam Type—Capacity, 5000 grams by 1/10 gram. The double beam makes it possible to weigh up to 110 grams without the use of weights. Above 110 grams, only weights of 100 grams and up are required, thus insuring speed and accuracy. The double beam is of great advantage when weighing material in containers, as no counterweights […]
Difference Between XRF and XRD
In summary, the difference between XRF and XRD is simple: XRF analyzes for Chemistry while XRD determines the mineralogy. XRD identifies and measures the presence and amounts of minerals and their species in the sample, as well as identify phases. XRF will produces and assay by giving information on the chemical composition of your sample without […]
Gold Jig DIY Plans Hand Operated
