Thin film technology creates the perfect combination for petrochemical analysis

Spectroscopists, chemists and lab technicians have a demanding job performing elemental analysis on many different types of materials. Crude oils, gasolines, diesel fuels are some of the most difficult materials to analyse in the petrochemical field. These materials contain aromatic and/or aliphatic hydrocarbons that tend to attack thin-film sample supports.  Severe cases of these hydrocarbons attacking the thin-film can lead to the thin-film sagging, called loading, leaking and even rupturing. Chemplex® has developed Etnom®, a thin-film sample support which has the unique property to resist chemical attack when exposed to aromatic or aliphatic hydrocarbons and eliminates any thin-film loading that may be present with Mylar® and polypropylene. The placement of the thin-film in the XRF analyser is crucial for consistent analytical results. Chemplex® XRF sample cups are engineered to position the thin-film sample support to the same position while maintaining a taught thin-film support plane. All Chemplex® XRF sample cups are made from virgin plastic to ensure no external impurities and are precision manufactured in a variety of sizes and features to fit any XRF analyser.
