What we test
Discuss your sample
A complete analytical package, under one roof.
Standard compendial methods or methods developed for your product. Each test is run in duplicate with system suitability and a documented review before release.
LC–MS/MS identity
Molecular weight confirmation, fragmentation and structural identity for APIs, peptides and impurities.
Residual solvents
Class 1, 2 and 3 solvent screening by headspace GC with FID, reported against ICH Q3C limits.
Elemental impurities
Trace metals and heavy elements by ICP-MS, aligned with USP <232> and ICH Q3D elemental limits.
Microbiological limits
Total aerobic count, yeast and mould, and specified organism screening for non-sterile products.
Method development
Feasibility, development and full validation of methods for new products, with a protocol you approve first.
Quality system
Built for regulated markets.
The people reviewing your data are the people who signed it. Every certificate can be traced back to the instrument, the analyst and the raw data file — for as long as the record must be kept.
01
Full traceability
Each report links to a laboratory record: instrument, calibration, analyst and raw data, retained for ten years.
02
Independent and impartial
No manufacturing interest in the products we test. We report what the data shows, including when it fails.
03
Validated methods
Specificity, linearity, accuracy, precision, LOD and LOQ documented before a method is used for release testing.
04
Confidential by default
Client names, sample details and results are never disclosed. Certificates are released only against a report number.
How it works
From sample to signed certificate.
STEP 01
Request & quotation
Send the sample details. You receive a quotation, a timeline and a sample submission form within one working day.
STEP 02
Sample intake
Samples are logged, photographed and sealed under a unique laboratory ID. You get confirmation the same day.
STEP 03
Analysis
Standard or client-specific methods, run in duplicate with system suitability checks and a second-analyst review.
STEP 04
Certificate issued
A signed PDF certificate with methods, results and chromatograms — protected by a report number you can verify.
Report access
Retrieve your certificate.
Every certificate carries a unique report number, printed on the first page and in the email we send with it. Enter the number to open the original PDF — no account required.
