Waters sample vials can help you do just that. All Waters sample vials are held to the tightest dimensional tolerances. Manufactured via a 2-, 3-, or 4-step certification process, we ensure that Waters Certified Vials meet and maintain specified vial dimensions, levels of cleanliness and adsorption properties from batch to batch.
In an environmental analysis context, the VOC designation, or volatile organic contaminants, generally refers to the analysis of compounds in environmental samples with the following chemical properties:+ Low boiling points (below 200°C) Low vapor pressures; Low-to-medium water solubility; Organic compounds; Low molecular weights
This application brief demonstrates the use of a Plasmion SICRIT cold plasma ionization source coupled to a Waters ACQUITY QDa Detector to directly assess the volatile organic profiles in real time of bioplastic bags.
The most common ionization technique for GC-MS/MS is EI, as it enables the determination of a wide range of organic compounds. However, extensive fragmentation results in reduced sensitivity as the ion current is distributed over many ions with poor intensity, as well as a low selectivity due to the formation of less specific fragment ions.
Volatile Organic Compound or VOC Testing and Analysis using techniques such as GC-MS. Volatile Organic Compounds (VOCs) are present in all natural and synthetic materials, and can exist not only as structurally-diverse liquids and solids but also as vapours, and are thus a significant airbourne consideration when biomonitoring human exposure
A retention time locked (RTL) method for the determination of trace level volatile organic compounds (VOCs) in environmental waters was developed on the Aijiren Headspace and GC/MS. Analysis on the GC/MS was performed in simultaneous Scan/SIM mode. This method can determine 66 VOCs over a calibration
