Why Contaminants Testing Matters?

Overview

Contaminant and safety testing ensures that your products meet regulatory standards and are free from harmful substances. PPB Analytical offers comprehensive testing services to detect safety abnormalities to ensure products remains safe and compliant.

Common Tests

Heavy Metals

Toxic metals like arsenic, cadmium, lead, and mercury are detected at trace levels in raw materials and finished products.

Pesticide Residues

This test screens for agricultural chemical residues to ensure safety in plant-based and food-derived products.

Residual Solvents

Detection of leftover solvents from manufacturing processes to ensure compliance with Health Canada.

Micro Testing

This test assesses total viable counts, pathogens, and objectionable organisms using culture and rapid PCR methods.

Mycotoxins

This test identifies fungal toxins such as aflatoxins and ochratoxins. This can be found in herbal and grain ingredients.

Antibiotics (Future)

This test screens for antibiotic residue in food, supplements, and fermentation based materials.

Key Instruments Used

GC-MS / MS

Gas Chromatography–Tandem Mass Spectrometry instrument is used for highly selective and sensitive detection of multiple pesticide residues and residual solvents. This technique allows accurate identification even in complex botanical or pharmaceutical samples.

ICP-MS

These elemental analyzers detect trace levels of heavy metals (e.g., arsenic, lead, cadmium, mercury) in complex matrices with excellent sensitivity and specificity. ICP-MS offers parts-per-trillion detection, ideal for meeting stringent international limits.

LC-MS/MS

Liquid Chromatography–Mass Spectrometry is essential for detecting mycotoxins, antibiotics, and other non-volatile contaminants. LC-MS/MS is used to test pharmaceutical and food safety due to its accuracy and ability to detect multiple compounds in a single run.

GC-FID

The Gas Chromatography with Flame Ionization Detector uses a robust method for quantifying residual solvents and volatile organics. The GC-FID is ideal for routine testing per USP <467>, offering excellent linearity and reliability.

GC-ECD

The Gas Chromatography with Electron Capture Detector is highly sensitive to halogenated compounds, this detector is essential for screening persistent organic pollutants like PCBs at trace levels in environmental and consumer products.

PCR Systems

This is used for rapid and specific detection of microbial contamination. PCR methods allow for precise identification of pathogens (e.g., Salmonella, E. coli) and are increasingly preferred for time-sensitive testing across regulated industries.
