Calibration curve

In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.[1] A calibration curve is one approach to the problem of instrument calibration; other standard

TOOLING: How to Select the Right Tool Steel for Mold

This steel also comes in a high-hard version (38-40 RC), and in lens grade when high surface-finish requirements are needed. P-20 is the first choice in most cases when using plastics without abrasive additives, but as I mentioned earlier, unless it's for very low-volume use, you will need to protect the steel against erosion with a coating or surface hardening.

Purified water

Purified water is water that has been mechanically filtered or processed to remove impurities and make it suitable for use. Distilled water was, formerly, the most common form of purified water, but, in recent years, water is more frequently purified by other processes including capacitive deionization, reverse osmosis, carbon filtering, microfiltration, ultrafiltration, ultraviolet oxidation

High Pressure Pigtail Selection Guide

Purity – Hoses that effuse gases can also diffuse gases. Diffusion can introduce contaminants that could effect the high purity gas stream. If this is a concern, consider using an all metal hose. Static State – If a gas is used in a static state, there will be times

Wafer (electronics)

In electronics, a wafer (also called a slice or substrate)[1] is a thin slice of semiconductor, such as a crystalline silicon (c-Si), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells. The wafer serves as the substrate for microelectronic devices built in and upon the wafer. It undergoes many
