Description of Industry

The chemical industry is a vast enterprise that affects everyone’s lives and ranges from large scale production of polymers and petro chemicals to specialty chemicals used for personal care.  Off-odors in chemicals, for example in polymers utilized for plastics, can be a major problem especially if the plastic is used for packaging foods, beverages or personal care items.  VAC specializes in detecting and measuring trace level off-odors caused by unknown contaminants.

Measurement of Organic Impurities in Water

Approximately 10g of liquid sample (sample A, B, C, D, E, F, G, H, I and J) were placed in 40mL clear vials and limonene was extracted using SBSE, or Twister, at room temperature for 90min. Twisters were heated to 280oC for 3 minutes inside a thermal desorption unit (TDU). The TDU transfer temp was 280oC and operated in splitless mode with purge time 1.00min. The target volatile generated during thermal desorption of Twister bar were swept onto a cryo-cooled (LN2) inlet liner at -90oC (CIS4 liner in split mode 20:1). The liner contained glass beads for increased adsorption. The liner was heated to 280oC for 3min and volatiles were...
