GC-MS Assist Pro™ — 1-Year Licence

Plan your GC-MS method before you book the instrument.

Type your analyte names. In a few minutes you get a scored starting method: column, inlet, oven programme, ion source and the ions to watch, all in your browser.

GC-MS Assist Pro™ is a method-development workspace for analytical chemists, built by a pharmaceutical analytical scientist. It shows its reasoning at every step, so you can judge the output instead of just accepting it.

WHAT YOU GET

AI Method Development

Add one compound or a whole panel by name. Formula, exact mass, XLogP, TPSA and 2D structure come live from PubChem.
Get a starting capillary column from a library of 7 GC-MS phases (DB-5ms UI, DB-1ms, Rxi-5Sil MS, DB-17ms, DB-624, DB-WAX, Rtx-VMS), with the reason it was chosen.
Get starting inlet, transfer-line and ion-source settings, plus a collision-energy ramp for GC-MS/MS.
See a derivatisation check for every analyte: silylation or methylation where free –OH, –NH or –COOH groups would tail, or confirmation that it can be injected as is.

Ions you can trust

Exact m/z for EI (70 eV) and CI (positive and negative), to four decimal places, with correct electron-mass handling.
Every ion is screened against the molecular formula, so you're never offered a loss the molecule can't make, such as a water loss from a hydrocarbon.

Live Method Quality Scorecard

Retention factor, resolution, plate count and Hagen–Poiseuille head pressure, re-scored as you edit the oven programme, column or carrier gas (He, H₂ or N₂).
Plain-language fixes. The retention check names your first and last eluting peaks, so a peak on the solvent front can't hide behind an average.

Chromatogram & Spectrum Studio

A predicted chromatogram with peaks numbered in elution order, a retention table, and an illustrative EI/CI spectrum for each analyte.

Method Optimizer

Sliders for column length, film thickness, flow, ramp time and collision energy, with every metric updating instantly.

And more

AI Troubleshooting: pick one of 8 common GC-MS symptoms (tailing, bleed, carryover, RT drift, discrimination, noise, air/water, split peaks) and get likely causes and fixes in order.
8 calculators: m/z, ppm mass accuracy, charge state, k, Rs, N, USP tailing, and column geometry and flow.
AI Assistant for GC-MS questions in plain language.
Method Library, plus a structured Method Development Report you can print or save as PDF.
An ICH / EPA / SANTE-aligned validation checklist with progress tracking.

HOW THE LICENCE WORKS

One 1-year licence, valid for 365 days from purchase.
Licensed per user. It activates on 2 devices (for example a work PC and a laptop), and you can move it between computers yourself with one click.
Nothing to install. It runs in any modern browser. Your licence key arrives on the Payhip receipt.
Your compounds and methods stay in your own browser and are never uploaded.
Includes the Welcome & Access sheet and a 19-page illustrated User Guide.

IMPORTANT

GC-MS Assist Pro™ is a development-support and training tool. It is not a validated computerised system, and its outputs are not GxP records. Retention times, resolution and spectra are model predictions: retention is estimated from XLogP and is most reliable within a compound class. Confirm every method on your own instrument before use.

Buying for your lab or company?

Pay by card or PayPal and download a PDF invoice with your company name and VAT/tax number from your receipt. Need an invoice before you pay, a purchase-order reference, or licences for 5 or 10 analysts? Email practicalpharma.science@yahoo.com with your company name, billing contact and number of users, and you'll receive a quote within one business day.
