Laboratory Excellence
Testing Services
Mineral Quality Services Pvt. Ltd. (MQS) operates advanced analytical laboratories that combine ISO/IEC 17025 rigour, NABL accreditation, and industry-specific insight to deliver precise, defensible data. Our scientists translate complex measurements into actionable intelligence for mine operators, trading houses, power utilities, steel makers, fertiliser producers, and engineering firms who demand confidence in every shipment and process stream.
From rapid screening during custody transfers to exhaustive method development for new energy materials, MQS aligns instrumentation, sampling strategies, and quality controls to the commercial context. We provide complete traceability, document decision logic, and maintain transparent communication through every testing milestone.
Scope of Services
MQS laboratories cover a broad testing spectrum that underpins material quality certification, process optimisation, environmental stewardship, and regulatory filings. Each service line is delivered by analysts trained in Good Laboratory Practice (GLP) and supported by validated methods documented within our LIMS.
Mineral & Fuel Analysis
Proximate, ultimate, and petrographic analysis of coal, coke, lignite, iron ore, manganese, bauxite, and industrial minerals with rapid turnaround commitments for shipping and blending decisions.
Metals & Alloys
Spectrometric and wet-chemical evaluation of ferrous and non-ferrous alloys covering chemical composition, inclusion rating, microstructure, and mechanical properties for foundries and OEM supply chains.
Environmental & Process Fluids
Testing of process water, effluents, lubricants, and hydraulic oils to meet ISO 14001 compliance obligations, desalination specs, and OEM warranty thresholds.
Construction & Infrastructure Materials
Aggregate, cement, fly ash, and admixture evaluation for density, fineness, chemical purity, and deleterious content supporting EPC and captive plant QA programs.
Sampling & Measurement Procedures
Laboratory accuracy is contingent on disciplined sampling. MQS collaborates with client operations, third-party inspectors, and logistics partners to implement statistically valid sample extraction, sub-splitting, and transport. Every field team receives method briefings, PPE matrices, and contingency plans addressing adverse weather, moisture drift, and contamination risks.
ISO 13909 and ASTM D7430 aligned sampling plans for coal and coke with auto-samplers, cross-belt cutters, and manual auger methodologies when equipment access is constrained.
Granular traceability records linking field sample IDs to laboratory login numbers, moisture correction factors, and witness seals verified by client representatives.
Replicate and referee sample retention policies enabling dispute resolution and inter-laboratory comparison without compromising chain-of-custody integrity.
Samples are logged into our LIMS immediately upon arrival, weighed for moisture correction, and stored under controlled conditions. Witness samples, reference materials, and blank inserts maintain statistical control, while photographic evidence supports custody narratives.
Laboratory Testing Capabilities
MQS laboratories integrate classical wet chemistry with state-of-the-art instrumentation. Analysts follow method-specific work instructions detailing reagents, calibration sequences, instrument set points, and quality checks. Round-the-clock operations ensure critical shipments are certified without delay.
ICP-OES, ICP-MS, and XRF platforms for multi-element suites, trace contamination monitoring, and alloy grade confirmation.
Thermogravimetric analyzers, bomb calorimeters, and carbon-sulfur determinators delivering critical parameters such as GCV, UHV, and sulphur content.
GC-MS, FTIR, and ion chromatography systems for organic residue identification, purity profiling, and ionic contamination assessments.
Complementary services include particle size distribution, rheology, filterability, corrosion testing, and humidity cycling. We also execute client-specific test methods under confidentiality agreements when proprietary formulations or pilot projects are involved.
Certifications & Compliance
MQS governance systems provide assurance that every certificate of analysis can withstand customer, regulator, or arbitration scrutiny. Compliance commitments span technical, ethical, and environmental dimensions.
NABL accreditation for mechanical, chemical, and biological disciplines, ensuring traceability to SI units and internationally accepted reference standards.
ISO/IEC 17025 compliant quality manuals, method validation records, uncertainty budgets, and proficiency testing participation demonstrating sustained technical competence.
Integration with ISO 9001, ISO 14001, and ISO 45001 frameworks guaranteeing consistent service delivery, environmental stewardship, and occupational safety.
Method revisions, change controls, and risk assessments are reviewed by an independent technical committee. Internal audits, supplier qualifications, and EHS drills reinforce our commitment to safe, compliant laboratory operations.
Documentation & Reporting
MQS translates raw data into clear, defensible documentation. Each report summarises sampling context, analytical techniques, measurement uncertainty, and conformance status versus contractual or statutory limits. Technical reviewers verify calculations, unit conversions, and narrative accuracy before release.
Laboratory Information Management System (LIMS) generated certificates with QR-coded authenticity checks and audit-ready metadata.
Statistical dashboards that visualise control charts, method precision, and historical performance for each product line.
Client-specific report templates capturing purchase order references, sampling plans, and release recommendations in a single consolidated PDF.
For clients managing multiple facilities, we provide consolidated month-end dashboards and API feeds to integrate laboratory KPIs into enterprise resource planning (ERP) or manufacturing execution systems (MES).

Frequently Asked Questions
What is the typical turnaround time for routine mineral testing?
Standard proximate and elemental suites are delivered within 24–48 hours of sample receipt, while specialised tests such as petrography or trace contamination may take 3–5 working days. Expedited plans are available upon request, subject to method stability considerations.
Can MQS support method validation or round-robin studies for our in-house lab?
Yes. We collaborate on method validation, bias studies, and inter-laboratory comparisons. Our scientists provide statistical design inputs, certified reference materials, and interpretation workshops so your lab can demonstrate equivalence with NABL and ISO 17025 expectations.
How do you assure data security and confidentiality?
All analytical data is stored within segmented networks with encryption at rest and in transit. Client contracts include confidentiality clauses, and only authorised personnel with multi-factor authentication can access project folders. Physical archives are housed in restricted zones with surveillance coverage.
