Chemical Analysis

The Chemistry Laboratory provides comprehensive analysis of food, cosmetic and allied products, supporting Nutritional Labelling, Product Safety, Product Stability and Quality Assurance.
Accredited full nutritional panels for accurate label declarations and product specs, including but not limited to: moisture, energy, protein, total fats, fatty acid composition, carbohydrates, total sugars, dietary fibre and ash. ISO 17025-accredited reports tailored for regulatory compliance, retailer submission and consumer-facing label.

Accredited quantification of fat- and water-soluble vitamins including vitamins A, B-complex, folate, B12, C, D, E, K using validated HPLC / LC-MS/MS methods. Ideal for fortified products, label claims and compliance testing – comprehensive reports with method details and expert interpretation when requested.

Trace and major element testing by ICP-MS/ICP-OES for elements such as lead, cadmium, arsenic, mercury, zinc, iron and essential minerals. Accredited, low-detection reporting to verify safety, meet statutory limits and support product specifications and supplier control.

Sensitive, accredited screening and quantification for priority allergens such as gluten, milk, soy, peanuts, tree nuts and egg using validated ELISA, lateral flow and molecular methods. Use for label declaration, supplier checks and contamination investigations – with rapid reporting and mitigation advice.

PCR-based species identification for meat, fish and plant origin to detect mislabelling, substitution or fraud. Accredited DNA testing provides definitive species confirmation for raw materials and finished products, supporting regulatory compliance and supply-chain assurance.
Quantitative oxidation testing such as peroxide value and free fatty acid content to assess oil quality, rancidity and shelf-life performance. Accredited chemical panels help validate formulations, storage and antioxidant effectiveness for reliable product quality.
Accredited multi-mycotoxin analysis such as aflatoxins, ochratoxin A, fumonisins, DON, zearalenone, patulin by HPLC-FLD / HPLC-UV for raw materials and finished foods. High-sensitivity reporting to protect consumer safety and meet regulatory and import/export requirements.

Comprehensive multi-residue pesticide screening and confirmation using GC-MS/MS and LC-MS/MS tailored to commodity matrices. Accredited pesticide panels for regulatory compliance, export requirements and supplier control, with clear reporting of detected residues.

Food-contact material testing including migration screening and element analysis to verify packaging safety and regulatory compliance. Practical reporting to support supplier approval, migration risk assessment and product-packaging compatibility.
Accredited screening and quantification of permitted dyes and detection of illegal colourants (e.g., Sudan dyes) using HPLC-DAD/UV and confirmatory methods. Ideal for label accuracy checks, safety assurance and regulatory compliance.
Screening and confirmatory testing for veterinary drug residues and antibiotics in animal-derived foods using validated LC-MS/MS methods. Accredited reporting against MRLs to protect consumers and meet regulatory/export requirements.

Comprehensive chemical and microbiological water testing packages for potable and process waters, including SANS 241-compliant drinking-water panels, turbidity, chlorine and targeted contaminants. Accredited testing to protect product safety and regulatory compliance.

Targeted contaminant screening such as PAHs, ethylene oxide residues, migration contaminants and other chemical hazards using GC-MS/MS and LC-MS/MS. Accredited testing for incident response, supplier control and product safety assurance.
Forensic-grade accredited testing for illicit adulterants such as melamine and other unlawful compounds using LC-MS/MS and confirmatory techniques. Rapid, defensible results to support investigations, recalls and regulatory actions.
