Quartz chips (1.2-2.5 mm granularity) are specialized reagents used in elemental analyzers for combustion processes. They serve as inert fillers or supports in sample tubes, providing high thermal stability and chemical inertness to withstand high temperatures (up to 1000°C) without reacting with samples or gases. Their high purity (typically >99.9% SiO2) ensures accurate elemental analysis results for carbon, hydrogen, nitrogen, sulfur, and oxygen in organic and inorganic materials.

Due to their hardness and abrasion resistance, these chips are also suitable for general laboratory applications like grinding media or filtration aids, but they are optimized for analytical instrumentation in research, environmental testing, and quality control industries.
