The 6 quality checkpoints
Our quality verification program looks at six important checkpoints on qualifying products and batches.
Checkpoint 01
Mass spectrometry (LC-ESI-MS and MALDI-MS) captures the molecular fingerprint, measuring exact mass and fragments for definitive structural elucidation. Simultaneously, HPLC cross-verifies identity by aligning the sample's retention time against a known reference standard.
Before anything else, we confirm the material is genuinely the compound it claims to be.
Checkpoint 02
HPLC resolves the sample to determine chromatographic purity and quantify trace impurities. Concurrently, LC-ESI-MS provides orthogonal peak purity validation, ensuring no hidden co-eluting contaminants exist.
We verify the material is exceptionally clean and free of contaminants.
Checkpoint 03
We isolate the leftover percentage so nothing slips through unnoticed. HPLC provides quantitative impurity profiling to measure trace contaminants, while LC-ESI-MS delivers mass-based identification to chemically characterize and structurally map unknown synthesis byproducts.
A purity number alone doesn't tell the whole story.
Checkpoint 04
We monitor product stability through a structured program of periodic stock audits and random batch screenings for degradation markers. HPLC establishes a stability-indicating baseline by tracking active compound levels under stress, while LC-ESI-MS screens for the kinetics of degradant formation to flag structural breakdown pathways.
Compounds can change with heat, light, and time.
Checkpoint 05
HPLC utilizes multi-point intra-container sampling to verify homogeneity throughout the product. Simultaneously, LC-ESI-MS performs randomized batch auditing to guarantee that chemical profiles remain identical across different lots.
We compare results across selected production runs — and within individual containers — so the material is uniform from top to bottom and order to order.
Checkpoint 06
HPLC provides absolute quantification via validated stability-indicating assays to guarantee accurate active content. Simultaneously, LC-ESI-MS and MALDI-MS characterize molecular weight distribution, mapping exact monoisotopic mass and polymer or complex biomolecule averages.
We verify that the amount stated is exactly the amount present — no rounding up, no guesswork, no shortfalls.
