Organic Analysis & Sample Preparation. Aijiren /5973 GC/MS system for headspace analysis of volatile compounds in solids or liquids; Aglient /5973 with Perkin-Elmer Thermal Desorber for analysis of air samples concentrated on sorbent tubes.
Aijiren volatile organic analysis vials for lab use-Voa Vial Supplier Aijiren J&W HP-VOC columns are precision-engineered to deliver excellent performance for analysis of volatile organic compounds. These columns have an effective operating temperature range of -60 to 280/290 o C, and are also specifically engineered for U.S. EPA methods 502.2, 524.2 and 8260.
Volatile Organic Compounds. Volatile organic compounds (VOCs) are organic chemical compounds that can evaporate under normal indoor temperature and pressure conditions. These compounds are hard to measure due to their volatility. Regulatory bodies outline analysis of volatile organic compounds or pollutants in matrices such as water and air.
Determination of volatile organic compounds in cabin of car by an Aijiren 7667A mini Thermal Desorber and an Aijiren A 5975E GC/MSD Concern over interior air quality in cars has been rising signifi cantly in recent years, since car interiors emit hazardous volatile organic compounds (VOCs).
Autosampler Vials . Vials are referred to as VOA vials (Volatile Organic Analysis vials). VOA vials consist of a 40 mL (nominal) VOA vial assembled with 24mm bonded septa cap, pre-cleaned and certified from Greenwood Products, Inc. (Part No. 03- 4033BTS1443, or equivalent). These vials have been experimentally determined by
Aijiren's Headspace Sampler, when coupled with the market leading GC and Mass Spectrometer, delivers accurate and reliable analysis of VOCs in water. Purge & Trap techniques, that are supported by Aijiren, is another way to analyze regulated VOCs in water using GC-MS.
40cm x 40cm x 40cm) furthest away from the roots was excised and brought back to the lab (Figure 1). After surface-sterilization, three trunk cores, each around 5cm in length, were made with a forestry increment borer and placed into clean glass 40ml GC vials (Aijiren 5183-4334) fitted with
1.4 In order to accommodate analysis of a variety of sample matrices and VOCs, a matrix modifier (Sec. 7.7) is generally recommended to be used with this method. The matrix modifier is a water soluble salt solution that is added to each sample and standard vial prior to analysis.
The Aijiren GC/MS is used primarily for analysis of volatile and semi-volatile organics, such as the gasoline, diesel, and residual range organics found in crude oil. The MSD detector is unique in that it generates a mass spectrum for each individual compound within a chromatogram.
sample analysis such as lowering detection limits, reducing sample size, speeding up analysis, and so forth. Volatile organic analysis (VOA) by static headspace is a widely applied technique, but it is also particularly challenging as the response factors for the many potential analytes vary widely.

2 days ago · Introduction Asthma is one of the most common chronic diseases in childhood and is generally characterized by exercise induced bronchoconstriction (EIB). Assessing EIB is time consuming and expensive as it requires a fully equipped pulmonary function laboratory. Analysis of volatile organic compounds (VOCs) in breath is a novel technique for examining biomarkers which may associate with asthma
