Determination of Volatile Organic Compounds in Water-Based Paints and Varnishes Using GC-MS

Capable of fast data measurement with sensitivity five times higher than previous models, the GCMS-QP2010 Ultra offers improved applicability for comprehensive two-dimensional GC and ultra-high separation. Shimadzu used new, patented mass spectrometry technology called Advanced Scanning Speed Protocol (ASSP™), a firmware protocol that optimizes the ion transmission hardware parameters with a highly efficient data collection algorithm, to increase data acquisition speed up to 20,000 u/sec and 100 Hz. ASSP also provides the added benefit of maintaining system sensitivity at elevated scan speeds. To help increase throughput, the GCMS-QP2010 Ultra features high-speed oven cooling for shorter analysis cycles. Using a double jet cooling system, the GC cools from 350 to 50 degrees Celsius in less than three minutes. The combination of a high-speed GC method and a high-speed cooling oven can reduce the analysis cycle by up to 50 percent. To further increase lab efficiency, the GCMS-QP2010 Ultra can accept two narrow-bore capillary columns into the MS simultaneously. Its twin-line MS system allows users to switch applications without physically modifying the column installation. Users simply decide which columns are required for analysis and choose the associated injection port.
