Gas Chromatograph – Mass Spectrometer (Quadrupole) with new ion optics system
Brief introduction of NBXD-8010:
Applications
The excellent performance of the GC-MS 3200 makes it suitable for applications in various fields including food safety, environmental safety, chemicals, among others.
1 Detection of Melamine in Milk
The detection limit is stable at 0.01 mg/kg. Linearity remains excellent between 0.05 - 50 mg/L. Recovery of added standard is between 85% - 108%. Relative standard deviation is less than 5%. Correlation coefficient is above 0.999. Results comply with GB / T 22388-2008 standard.
2 Analysis of Volatile Organic Compounds (VOC) in Drinking Water or Surface Water
Using external standard method, range of linearity is 0.5 - 100 μg/L. Correlation coefficient of each component is between 0.993 ~ 0.9992. The lowest detection limit is 0.001 mg/L for vinyl chloride. The instrument shows excellent performance in VOC analysis of drinking water in compliance with EPA method 502.2 and GB5749-2006.
3 Detection of Plasticizer in Liquors
16 types of phthalates in liquor are analyzed simultaneously. Range of linearity is 0.08 - 1.6 ug/mL. Recovery of added standard is between 70% - 119%. The lowest detection limit achieved is 1.06 ug/kg for DEP. Shows excellent contamination resistance. After 1 month of continuous use, background signal remains within spec.
4 Trace PAHs Detection
Linear correlation coefficient is more than 0.999 in the concentration range of 0.05 - 0.5 ug /mL.
Relative standard deviation is less than 6%. The lowest detection quality for benzopyrazole is 0.05 ng.
5 Detection of Organochlorine Pesticide
In ion monitoring mode, the analysis of organochlorine pesticide provides reliable data. Range of linearity is 0.012 - 0.2 ug/mL. Relative standard deviation is less than 10%. Lowest detection concentration reaches 0.012 ug/L.
