Sub-Visible Particulate Matter Testing
NABL-accredited sub-visible particle testing per USP 788 (injectables), USP 787 (biotechnology products), and USP 789 (ophthalmic preparations) — three separate pharmacopoeial workflows with different acceptance limits, plus WFI and ISO 14644 cleanroom monitoring. Particle Measuring System operated at our Delhi flagship lab.
Six confirmed liquid particle counter application areas. USP 788, USP 787, and USP 789 are described as three separate pharmacopoeial tests, each with its own scope and acceptance limits.
Sub-visible particle testing per USP 788 (light obscuration plus microscopic referee method). LVP no more than 25 particles/mL at 10 micrometers and 3 particles/mL at 25 micrometers; SVP no more than 6000 particles/container at 10 micrometers and 600 at 25 micrometers.
Sub-visible particle testing for protein-based biologics per USP 787. USP 787 has different acceptance limits and applicability than USP 788 — lower sample volume, protein aggregate considerations — and is described as a separate test.
Particulate matter testing for ophthalmic solutions and suspensions per USP 789 — a third separate test with its own scope and acceptance limits distinct from USP 788 and USP 787.
WFI particle count monitoring for pharmaceutical water systems per USP 643, USP 1231, and IP requirements. Supports water system commissioning, performance qualification, and routine GMP monitoring.
Cleanroom particulate environmental monitoring per ISO 14644-1 and ISO 14644-2 supporting pharmaceutical manufacturing GMP qualification, classification, and ongoing monitoring of Grade A/B/C/D environments.
Particle screening for Purified Water systems in pharmaceutical and cosmetic manufacturing per USP 643 and EP monographs — detecting biofilm shedding, filter failures, and distribution-loop contamination events.
Three separate tests — not one: USP 788 (injections), USP 787 (biotechnology products), and USP 789 (ophthalmic preparations) have different acceptance limits and applicability. Quotes specify which pharmacopoeial test applies to your product and matrix.
Particle Measuring System (PMS) at the Delhi flagship lab, operating on the USP 788 light obscuration principle with a detection range of 1 to 100 micrometers in the liquid phase.
Particle Measuring System (PMS) liquid particle counter operated at the Delhi flagship lab supporting injectable pharmaceutical QC and water system monitoring workflows.
Light obscuration methodology per USP 788. The collimated light beam detects each particle by the proportional reduction in transmitted light intensity, sizing and counting particles in real time.
Detection range of 1 to 100 micrometers in the liquid phase — covering the sub-visible particulate window relevant to USP 788, USP 787, and USP 789.
Reported counts at the >=10 micrometer and >=25 micrometer particle thresholds specified in USP 788 for both large-volume and small-volume parenterals.
Method validated for USP 787 biotechnology product testing and USP 789 ophthalmic preparation testing — separate workflows with separate acceptance criteria from USP 788 injectables.
Specific instrument make and model to be confirmed with the lab team before publishing. Calibration traceable to certified polystyrene latex (PSL) sphere standards.
Three industries served by liquid particle counter testing — pharmaceuticals, medical devices, and pharma-grade water systems.
Injectables, parenterals, and lyophilised reconstituted products requiring sub-visible particle testing per USP 788, USP 787, and USP 789.

Single lab for injectables (USP 788), biotechnology products (USP 787), and ophthalmic preparations (USP 789) — three separate pharmacopoeial workflows under one accredited roof.
GLP-compliant data generation for regulatory submissions — raw data, instrument logs, and validation records aligned with CDSCO and USFDA expectations.
NABL-accredited results accepted for CDSCO submissions, USFDA dossiers, EU regulatory packages, and CDSCO-recognised international filings.
Liquid particle counting pairs with these complementary techniques across the Auriga analytical platform.
For particle identification — once sub-visible particles are isolated, FTIR identifies their composition (rubber, silicone, polymer, glass, protein aggregate) for root-cause investigation.
