The most common method of analysis for Benzoylecgonine is Gas-Chromotography Mass-Spectometry (GC-MS). This is considered the ‘gold standard’ in commercial drug testing. GC-MS is a specialised analytical method that, until recently, wasn’t offered by many laboratories due to its complex (and expensive) ‘two-stage’ analytical process.

Vial Crimpers and Vial Decappers. We are specialists in the design and manufacture of quality vial crimpers and vial de-cappers for crimping aluminium caps onto vials and bottles as well as de-capping (de-crimping). If it’s a crimper or a de-capper you need, then we have the tool to suit as we have been producing them for nearly 30

Common derivatization techniques used in reaction headspace/GC are esterification, acetylation, silylation, and alkylation. Any of these derivatization techniques can be performed using the sample vial as the reaction vessel (see Table III for a list of

Analytical Vials. Vials play a significant role in analytical analysis and result reproducibility. Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified, application-specific, contaminant-free vials can significantly reduce risk. We offer a broad spectrum of Supelco ® products including

Results of using re-washed vials and closures TECHNICAL NOTE 20670 Introduction When using glass autosampler vials in the laboratory, standard workflows require that vials and closures be considered consumable items and that they are discarded after each

The most commonly used vials are 9mm, 12x32mm screw thread vials. A 12x32mm vial is also known as 1.5mL, 1.8mL, and 2.0mL vials by different manufacturers. Microsampling options include using a one-piece vial with fused insert molded into the vial, or using a separate insert placed into a vial. Our 13mm vials are 4mL vials for larger volumes

The processing conditions used to manufacture glass vials can be designed to mitigate the potential for later delamination. Drug solutions formulated at high pH (alkaline) and with certain buffers.
