Advanced Pesticide Testing Services Backed by GC-MS Expertise in Canada
Quantitative pesticide residue analysis for pharmaceuticals, food, agriculture, and environmental samples.
At ResolveMass Laboratories Inc., we provide reliable pesticide testing services using advanced GC-MS technology. As a trusted name in analytical chemistry in Canada, we focus on detailed chemical analysis and impurity profiling for complex samples—whether it’s food, water, soil, cosmetics, or pharmaceuticals. Our team of Ph.D.-level analytical chemists follows strict FDA-compliant GC-MS procedures to detect even the smallest traces of pesticide residues, helping our clients confidently meet international regulations.
Why Accurate Pesticide Testing Matters
Pesticide residues can cause serious health risks and threaten environmental safety. Whether you work in pharmaceuticals, food production, agriculture, or cosmetics, regulatory agencies like Health Canada, the FDA, and the EU enforce strict limits on pesticide levels. Reliable Pesticide Testing Services help manufacturers ensure their products are safe, avoid costly recalls, and maintain consumer trust.
At ResolveMass, we use highly sensitive gas chromatography-mass spectrometry (GC-MS) methods to detect and measure pesticides at extremely low concentrations—down to ppb and even ppt levels—so your products comply with global standards.

FAQs
Pesticide testing typically involves extracting residues from the sample matrix (such as food, soil, or water), followed by analysis using advanced instruments like gas chromatography-mass spectrometry (GC-MS). The process includes sample preparation, cleanup to remove interferences, and detection of specific pesticide compounds.
Pesticides can be detected through highly sensitive techniques such as GC-MS and LC-MS/MS, which separate and identify the individual pesticide molecules based on their mass and structure. These methods are capable of detecting pesticide residues at extremely low concentrations—often in ppb or ppt. The use of selective ion monitoring and spectral libraries helps confirm the presence of specific compounds even in complex matrices like food or soil.
The correct way to measure pesticides involves using quantitative analytical methods that follow regulatory guidelines, such as those from the FDA, EPA, or Health Canada. Instruments like GC-MS/MS are used along with calibration standards and quality control samples to ensure measurement accuracy. The entire workflow—from sample extraction to final reporting—must be validated and documented to meet international compliance standards.
GC (Gas Chromatography) analysis of pesticides involves separating volatile pesticide compounds from a sample and identifying them using a detector, often coupled with mass spectrometry (GC-MS). This technique is especially effective for analyzing organochlorines, organophosphates, and pyrethroids. GC-MS provides both qualitative identification and quantitative measurement, making it a gold-standard method in pesticide residue analysis.
The most widely used method for pesticide testing is gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS), depending on the compound’s volatility and chemical nature. Multi-residue methods (MRMs) are often employed to detect multiple pesticide types in a single analysis. ResolveMass Laboratories uses FDA-compliant, validated methods tailored for each sample matrix to ensure reliable results.
To identify the presence of pesticides, analytical labs typically use techniques like GC-MS or LC-MS/MS, which offer high sensitivity and selectivity. These methods rely on the molecular signature of each pesticide, comparing the sample’s data with known reference standards and spectral libraries. The approach ensures both accurate detection and compound-specific identification, even at very low concentrations.
Pesticide residue analysis commonly uses instruments such as gas chromatography-mass spectrometry (GC-MS), liquid chromatography-mass spectrometry (LC-MS/MS), and high-performance liquid chromatography (HPLC). These tools allow precise identification and quantification of pesticide residues across various sample types. At ResolveMass, we use advanced GC-MS/MS systems equipped with advanced detectors and data processing software for ultra-trace analysis.
