Gas chromatography (GC) and high‑performance liquid chromatography (HPLC) are the workhorses of pharmaceutical QC. But mass spectrometry (MS) is the fastest‑growing technology. The pharmaceutical quality control market research shows that MS is growing at over 10% CAGR, because it can identify unknown impurities at parts‑per‑billion levels. If a drug is contaminated with a genotoxic impurity, MS will find it.
What's new? LC‑MS/MS (liquid chromatography tandem mass spectrometry) for biologics — measuring monoclonal antibody aggregates and fragments. Also, GC‑MS for residual solvents and extractables. The pharmaceutical quality control market trends highlight that chemical testing is the largest testing type, but microbiological testing is the fastest‑growing — because of the rise of sterile biologics and cell therapies.
But MS instruments are expensive ($200k‑$500k) and require highly trained operators. That's why many small pharma companies outsource to contract labs.
The bottom line: if you're a QC manager, invest in MS. It's not cheap, but it could save you from a recall that costs millions.
