The Negative Impact of Inclusions in Metallic Alloys for GC and LC Components and Analyses

Dr. Jesse Bischof will present his latest data on the impact of inclusions in metallic alloys and their negative impact on GC and HPLC analysis. Dr. Bischof will cover the origins and impact of inclusions of common alloys and their direct effects on instrumentation and consumables.

Event Overview:

Both gas and liquid chromatography systems utilize stainless steel and other metallic alloys for components such as tubing, valves, sampling needles, columns, and more. Due to the high demands in the semiconductor and pharmaceutical industries, as well as supply chain disruptions from COVID-19, high quality stainless steel has become very difficult to acquire. This has led many machine shops and instrument manufacturers to seek out new sources of steel materials. While the bulk metallic composition falls within the ranges and limits to be classified as 316 Stainless steel, the microstructure of such alloys is often overlooked, specifically the impact that inclusions in the steel can have on instrumentation and consumables. Here we explore the origins of inclusions in stainless steel, such as manganese sulfides or silicon rich chromium oxides and the impact that these inclusions can have on the chemical and physical properties of stainless steel. Additionally, the impact these inclusions can have on SilcoTek Corporation’s coatings, such as SilcoNert 2000 (aka Sulfinert) for gas chromatography and Dursan for liquid chromatography will be discussed.

Key Learning Objectives:

• How inclusions in metals can impact gas and liquid chromatography in a variety of industries requiring purity including pharmaceutical and semiconductor applications
• How to avoid negative effects of metal inclusions in analyses through thoughtful surface material selection

Who Should Attend:

• Researchers
• Product Engineers
• Chemists
• Those interested in metal contamination and its effect on chromatography and analysis
