D. Analyticals (DALPL)

Doctors' Analytical Laboratories Private Limited, widely known by its registered acronym DALPL, is an independent accredited contract testing organisation (CTO) headquartered in Navi Mumbai, Maharashtra, India. Founded in 2006 and operating under the mission statement 'Testing For a Better World,' DALPL provides a complete range of routine and advanced analytical testing services to manufacturers, exporters, importers, quality-assurance departments, and regulatory bodies across India and internationally. The laboratory occupies two purpose-built units within the TTC MIDC industrial zone: Unit 1 at R-809, Thane–Belapur Road, Rabale, Navi Mumbai – 400701, which houses the Food, Agri, and Water Testing Division; and Unit 2 at B-49, Shruti Flexipack, First Floor, MIDC Road, TTC Industrial Area, Airoli, Navi Mumbai – 400708, dedicated to pharmaceutical analysis. This dual-site structure enables DALPL to segregate food and pharma workflows in compliance with the distinct regulatory requirements governing each sector.

The Food and Agriculture Division is DALPL's flagship capability and the source of much of its regulatory recognition. The laboratory accepts a wide range of food matrices — cereals, pulses, spices, condiments, herbs, edible oils, dairy products, processed foods, snacks, fruits, vegetables, and raw agricultural commodities — for both export-compliance and domestic food-safety testing. Core analytical programmes include multi-residue pesticide screening by GC-MS/MS and LC-MS/MS, heavy-metal determination (lead, cadmium, arsenic, mercury, chromium, copper, and zinc) by atomic absorption spectroscopy (AAS), mycotoxin and aflatoxin quantification, veterinary drug and antibiotic residue analysis, ethylene oxide and 2-chloroethanol residue testing, and testing for organic produce certification. The laboratory is empanelled with the Food Safety and Standards Authority of India (FSSAI) and is recognised by APEDA (Agricultural and Processed Food Products Export Development Authority) and SPICEBOARD, enabling it to issue test reports that satisfy Indian statutory and export-documentation requirements.

Nutritional analysis and label-claim verification form a major service line for food producers, nutraceutical brands, and supplement manufacturers. DALPL performs full proximate analysis (moisture, protein, fat, crude fibre, ash, and carbohydrates), energy calculation, dietary-fibre panels, micronutrient and vitamin assays, and the preparation of nutritional fact panels in formats aligned with FSSAI, US FDA, European, and other international labelling regulations. The laboratory also conducts food shelf-life testing and stability studies — including accelerated and real-time protocols — to establish best-before dates and evaluate packaging compatibility over time, supporting product-development teams seeking to launch or re-formulate packaged foods and supplements.

Microbiology testing spans the complete range of indicator organisms and pathogens mandated by food, water, and pharmaceutical quality standards. Analyses include total viable count, total coliform and E. coli enumeration, Salmonella spp., Listeria monocytogenes, Staphylococcus aureus, yeast and mould counts, and Bacillus cereus, conducted under ISO, BIS, and AOAC reference methods. Water testing is a parallel service line, covering drinking water, treated and process water, and effluent for physicochemical parameters, residual chlorine, turbidity, hardness, total dissolved solids, heavy metals, pesticide residues, and full microbiological quality — benchmarked against BIS IS 10500, WHO guidelines, and client-specific specifications. These services support municipal utilities, industrial facilities, beverage manufacturers, and environmental-compliance programmes.

The Pharmaceutical Testing Division, operated from Unit 2 in Airoli, holds an independent complement of approvals and inspections entirely separate from the food unit. DALPL is registered with and has been successfully inspected by the US Food and Drug Administration (USFDA), holds approval from Health Canada, and is licensed by the Maharashtra State FDA — a combination of North American and Indian regulatory acceptance held by only a select group of Indian contract testing laboratories. Services in this division include finished dosage-form testing (tablets, capsules, liquids, injectables), raw-material and excipient identification and purity testing, elemental impurity profiling per ICH Q3D, dissolution and disintegration studies, assay determination by HPLC, stability testing per ICH Q1A guidelines, and microbial-limit testing for pharmaceutical products. These capabilities serve generic-drug manufacturers, API producers, and pharmaceutical exporters who need data packages acceptable to USFDA, Health Canada, and Indian drug authorities.

The laboratory's analytical instrument platform supports a broad range of separation, detection, and characterisation techniques. Confirmed equipment includes LC-MS/MS (Waters), GC-MS/MS (Varian 4000), HPLC with UV and fluorescence detection (Waters Alliance), GC with electron-capture detection (GC-ECD) for chlorinated pesticides and GC with flame-ionisation detection (GC-FID) for solvents and hydrocarbons, atomic absorption spectroscopy (AAS) for elemental analysis, UV-visible spectrophotometry, and Fourier-transform infrared spectroscopy (FTIR) for identity and structural characterisation. This multi-platform configuration enables low-detection-limit quantification of trace contaminants, residues, and active pharmaceutical ingredients across complex food, environmental, and pharmaceutical matrices.

DAPL's quality infrastructure underpins all analytical output. Unit 1 holds NABL (National Accreditation Board for Testing and Calibration Laboratories) accreditation in full conformity with ISO/IEC 17025:2017 (certificate TC-13569), the internationally recognised benchmark for testing laboratory competence. The laboratory additionally carries GMP+ certification for feed-safety testing, FSSAI empanelment for statutory food analysis, and formal recognition from SPICEBOARD and APEDA for Indian export certification. The pharmaceutical unit's USFDA registration and Health Canada approval demonstrate that DALPL's data-integrity protocols, documentation practices, and quality-management systems meet the exacting standards of North American drug regulators. Collectively, these accreditations and approvals make Doctors' Analytical Laboratories a credible, multi-sector analytical partner for clients who require test results recognised by Indian, US, Canadian, and international regulatory authorities.
