Time：27.05.2026What are the differences between a gas permeability tester (differential pressure method) and an oxygen permeability tester (coulometric method)? Which one should be chosen for high barrier materials? This article provides an in-depth comparison from four aspects—principle, accuracy, standards, and cost—offering clear selection recommendations to help you avoid choosing the wrong equipment. -
Time：18.05.2026Detect harmful solvent residues in flexible packaging with a gas chromatograph for packaging. Ensure food & pharma safety. Headspace GC method. Meet compliance. -
Time：08.05.2026In industries such as flexible packaging, food, pharmaceuticals, and photovoltaics, the Water Vapor Transmission Rate (WVTR) is a core metric for evaluating material barrier properties. However, during the selection process, many users find that despite comparing numerous spec sheets, the purchased instrument either fails to measure actual samples, shows poor repeatability, or is too cumbersome for daily use. -

Time：14.01.2026In the packaging industry, the integrity of a material’s barrier against gases is paramount for product preservation and shelf life. Reliable measurement of oxygen ingress is a fundamental laboratory requirement. For labs conducting packaging research, quality control, and compliance testing, selecting a high-performance Oxygen Transmission Tester is a critical decision. -
Time：25.12.2025In the precise world of gas chromatography (GC) analysis, the integrity of the final result is only as good as the sample introduced into the instrument. For volatile organic compounds (VOCs) present in solid or liquid matrices, Headspace Sampling has long been established as the preferred sample introduction technique. It offers a cleaner, more efficient, and reproducible alternative to direct liquid injection or complex solvent extraction. -
