The internal standard dropped 40% and nobody can tell you why.

Five practical resources for regulated bioanalysis.

$130 separately. $69 together.

Ion suppression never announces itself. It arrives as a recovery that won't reproduce, an internal standard that drifts between runs, an incurred sample reanalysis that fails at the worst possible moment, on a method that worked perfectly on neat standards.

LC-MS problems are rarely in the mass spectrometer. They're in the matrix, the extraction, the transitions someone chose two months ago, and the assumptions nobody wrote down.

This library is what I wish had been on my desk the first time I had to defend a bioanalytical method.

What's inside

• Bioanalytical LC-MS Method Development & Validation to Regulatory Standard - the full route, built to what regulators actually ask for.
• LC-MS Practical Guide - principle, method development, method validation.
• The Practical LC-MS Troubleshooting Atlas - visual diagnosis by symptom: suppression, carryover, adducts, response drift, poor recovery.
• LC-MS - 6 Practical Courses
• LC-MS Bioanalytical Assay Method Validation - validation report and Excel calculation templates, ready to fill in.

Who it's for

Bioanalytical scientists, LC-MS/MS method developers and validation leads working to ICH M10 in regulated bioanalysis, pharma, biotech and CRO laboratories.

Who wrote it

Mirela Gorjanu, MSc - senior pharmaceutical chemist, twenty years in drug development and compliance, including bioanalytical LC-MS/MS. Written from methods that had to survive an audit.

What it costs

$130 if you bought the five separately. $69 for the library.
