GC/MS-MS Applications
|
|
Pesticide Determination at 0.01 mg/kg
A huge number of different pesticides are
being regularly applied in the agricultural
industry, including insecticides,
fungicides, herbicides, and growth
regulators.
The inherent superior selectivity of GC/MS-MS
allows interference-free
quantification and positive confirmation of various pesticides in a
single analytical run, even with coeluting
compounds.
This application note shows the capabilities of the CHROMTECH
EVOLUTION MS/MS triple quadrupole
mass spectrometer utilyzing MRM Technique for multi-pesticides
residue analysis.

Analysis of PCBs in Fish Tissue
Low level PCB contamination can be monitored by analyzing fish tissue. Congener-specific analysis of the PCBs in fish
tissues is often performed by GC-ECD or GC-MS. Unfortunately, both techniques suffer significant limitations due to the often huge amount of matrix compounds
found in the sample extracts. This application note describes the successful use of the
CHROMTECH EVOLUTION Triple Quadrupole GC-MS/MS system for the analysis of PCB in fish tissue. The selectivity of Evolution GC-MS/MS is used to increase sensitivity
and minimize matrix effects while greatly reducing the possibility of false positives.

Herbicide Residues
This short application describes the use of
the Chromtech Evolution GC/MS-MS in combination with a quick sample
extraction procedure in the analysis of herbicide residues.
Demonstrating GC/MS-MS is extremely effective
for overcoming highly suppressing matrix effects that often plague single quadrupole
instruments.

Triple Quadrupole MS: MRM the Method of Choice for Complex Samples
Improper and/or illicit use of pesticides
on agricultural produce can cause
unacceptable high levels of their
residues in produce intended for human
consumption.
Worldwide there are over 800
compounds currently in use,
Food safety concerns are increasing
among consumers worldwide.
This application note compares the
results of SIM versus MRM using the
CHROMTECH EVOLUTION MS/MS
triple quadrupole mass spectrometer for
Tebuconazol in a real sample extract.

Determination of Cannabis Metabolite in Hair - (THC-COOH)
Utilizing the Chromtech Evolution GC/MS-MS for determination of the metabolite THC-COOH from a human hair sample for
the detection of cannabis use within the last 30 days of its consumption.
The CHROMSYS Evolution is controlled via Chemstation. An additional window is added within Chemstation for the
Evo SIM/Scan parameters in which the user can choose the parent/daughter ions as
well as the collision energy for each compound to be analyzed.

Evolution-GC/MS-MS: Analysis of Doping Confirmation Compounds
Derivatized (TMS) urine samples were used
to check the sensitivity and linearity for some
commonly known substances in the
field of doping analysis.
We adjusted the GC/MS-MS parameters as
close as possible to the values that are
used at this customer´s lab.
and checked the performance of this upgraded 6890N/5973 Evolution
Triple Quad system.
