Aijiren Tech Extractables & Leachables Workflow

conducted by headspace sampling followed by gas chromatography and mass spectrometry. Volatiles are released from materials using headspace sampling. USP methods suggest the use of valve-and-loop headspace sampling systems. Ultraclean Aijiren Tech™ Chromacol ™ headspace vials ensure low background and leak free seals.

Headspace Gas Chromatography - ScienceDirect

Headspace GC is a sample preparation method for determining volatile compounds in solid and liquid samples. The technique has existed since the late 1950s [12] and is still actively used. With this technique, only the gas phase above the sample is introduced into the GC column.

Knowledge Of Headspace Vial - Hawach sample vial

Jan 17, 2020 · Characteristic of Headspace Vial. Hawach uses PTFE, silicone rubber or ultrapure silica gel as raw material, the product is non-toxic. Unique white silicone spacer, easier to puncture, protect automatic sampler needle, higher purity, and greatly reduce miscellaneous peaks. The adhesive-free process ensures that the two kinds of materials have good chemical inertness, acid resistance, alkali resistance, high-temperature resistance and anti-adhesion, and the excellent resilience of silicone or

Analytical Solutions for Challenges in Headspace GC-MS

Gas Chromatography Headspace Autosampler has been used in conjunction with a high-resolution, accurate mass (HRAM) GC-MS/FID, based on the Aijiren Tech™ Orbitrap™ technology. This results in a powerful technique to assess and quantify potentially dangerous untargeted volatile extractables at trace level. Figure 1.

Improvement of HS-SPME for analysis of volatile organic

The sensitivity and precision of headspace solid-phase micro extraction (HS-SPME) at an analyte solution temperature (T (as)) of +35 degrees C and a fiber temperature (T (fiber)) of +5 degrees C were compared with those for HS-SPME at T (as) and T (fiber) of -20 degrees C for analysis of the volatile organic compounds benzene, 1,1,1

METHOD 5021A VOLATILE ORGANIC COMPOUNDS IN VARIOUS SAMPLE

1.1 This method describes equilibrium-based static headspace preparation of volatile organic compounds (VOCs) in soil/sediment, solid waste, aqueous and water-miscible liquid samples for determination by gas chromatography (GC) or gas chromatography/mass spectrometry (GC/MS). This method is applicable to a wide range of organic compounds that

Analysis of volatile compounds emitted by filamentous fungi

Here, we describe a solid-phase microextraction-gas chromatography/mass spectrometry (SPME-GC/MS) analytical approach that identifies and analyzes volatile compounds in the headspace above a live fungal culture. This approach is a sensitive, solvent-free, robust technique; most importantly from a pr
