Gas-powered fusion furnaces are often misconceived as inefficient and unsafe compared to electric alternatives, which utilize high-temperature silicon carbide (SiC) heating elements to melt samples in platinum crucibles. However, there are numerous advantages to gas fusion, particularly when coupled with specialized platinum labware.

This blog post will outline the Phoenix platinum crucibles from XRF Scientific, alongside some of the benefits of gas fusion for x-ray fluorescence (XRF) and inductively-coupled plasma (ICP) sample preparation.

Inductively coupled plasma (ICP) spectroscopy is an advanced analytical technique used for trace level determination of a sample’s elemental constituents. This is achieved by directing nebulized sample material through the plasma torch array that is charged with an electromagnetic coil. Liquidized droplets of the sample of interest are passed through the torch in a channel of gas. Ionized particles are then obtained from the plasma unit and transferred to a mass spectrometer, where they are sorted by mass-to-charge characteristics and analyzed using precise photodetectors. This enables analysts to determine the sample’s elemental concentration on the parts per million (ppm) range.

ICP applications are primarily concerned with the determination of elements and chemical contami...
