At Qalitex Laboratories, we provide specialized chemistry lab testing services designed for regulatory compliance, consumer safety, and product integrity. Our ISO 17025 Accredited  laboratory serves dietary supplement, cosmetic, personal care, and dry food brands that require high-precision testing for both raw materials and finished goods. Whether you’re preparing for market entry, routine quality control, or regulatory submission, our team delivers timely and accurate results aligned with FDA, USP, AOAC, and ICH test standards.

Our chemistry testing capabilities are uniquely suited for solid or powder-based products, including capsules, tablets, teas, plant extracts, face masks, and dry food products like rice, grains, or spices. 

Identity Testing

Qalitex Laboratories tests the authenticity and presence of active ingredients in your raw materials or finished products.

We use USP, AOAC, and in-house validated methods to identify compounds in complex matrices, ensuring your botanical extracts, herbal supplements, or cosmetic actives meet regulatory requirements. This step is essential to protect against adulteration, ensure proper labeling, and comply with FDA and cGMP requirements. We often use HPLC, FTIR, and UV-Vis spectroscopy to establish compound identity in powdered and encapsulated products.

Purity Testing

Evaluate the presence and quantity of unwanted compounds, excipients, or degradation products in your formulation.

Purity is a key parameter in product quality and directly impacts label claim accuracy, consumer safety, and shelf stability. Qalitex Laboratories  performs quantitative analysis of active ingredients and detects impurities, even in low concentrations. Whether you are manufacturing a multivitamin capsule or an herbal skincare balm, our chemistry testing services ensure that what’s on your label matches what’s in your product.

We use HPLC, UV-Vis, and titration techniques, and tailor test methods to your product’s unique matrix.

Contamination Screening

Ensure your products are free of unintentional contaminants such as residues, cross-contamination, or degradation byproducts.

Contamination in supplements or personal care products can come from raw materials, packaging, or processing environments. Qalitex offers comprehensive screening for unknown or known contaminants, including cross-contaminants, residual processing agents, and microbial toxins. All tests are conducted under ISO 17025-compliant procedures using validated techniques such as GC, HPLC, and FTIR.

Contamination screening supports compliance with FDA Good Manufacturing Practices (21 CFR Part 111) and industry quality standards like NSF/ANSI 173.

 Heavy Metal Testing

Comply with Prop 65 and international safety standards through precise heavy metal screening.

Qalitex Laboratories  provides chemistry testing for arsenic, cadmium, lead, and mercury in line with USP <232>/<233>, ICH Q3D, and California Prop 65 requirements. Heavy metals can accumulate in plant-based materials, soil-grown herbs, and raw food ingredients, posing risks to consumer health and brand reputation.

We use ICP-MS for ultra-trace level detection and offer batch certificate documentation for regulatory filings.

Pesticide Residue Testing

Protect your customers and meet regulatory guidelines with pesticide screening for plant-based materials.

Our pesticide chemistry testing covers multi-residue panels using GC-MS and LC-MS instrumentation, tailored for herbal supplements, botanical teas, and functional foods. Whether you source from organic farms or mass suppliers, verifying the absence of harmful residues like glyphosate or organochlorines is critical to maintain product integrity.

We follow USP <561>, EPA, and EU Annex II methods and provide limit of detection (LOD) data as needed.

Residual Solvents Testing

Ensure solvent levels comply with USP <467> and meet international safety thresholds.

Residual solvents may remain from botanical extraction or formulation processes. Qalitex Laboratories  offers volatile organic compound (VOC) testing using headspace GC to identify and quantify Class 1, 2, and 3 solvents. Our chemistry testing service helps you stay compliant with regulatory limits and demonstrate adherence to Good Manufacturing Practices.

---

Quantitative Assay

Verify that your products contain the labeled amount of active ingredients.

We perform HPLC-based quantitative assays to confirm potency and consistency in finished goods. This is essential for claim verification on supplements, personal care actives, and over-the-counter (OTC) topical products. Our assays are aligned with USP monographs or client-specified targets and support batch release, product launches, or audit documentation.

---

Method Development & Validation

Custom testing for novel or proprietary products requiring specialized analysis.

For unique formulations or emerging actives, Qalitex offers full analytical method development, validation, and transfer services. Our chemists work with your R&D team to design fit-for-purpose test methods aligned with ICH Q2(R1), USP, and AOAC guidelines. Whether you’re developing a new skincare active or launching a supplement with unusual plant extracts, we ensure the method is robust, reproducible, and scalable.

---

Spectrophotometric Analysis

Fast, cost-effective chemistry testing for product screening or compound confirmation.

Qalitex Laboratories offers UV-Vis and FTIR spectroscopy to detect and quantify compounds in cosmetic creams, personal care products, and botanical powders. These techniques are ideal for routine quality control and identity verification, especially when turnaround time or cost efficiency is critical.

Spectrophotometric methods are validated under USP and in-house protocols.
