Reconstitution and dose-volume calculator
Bacteriostatic-water volume to concentration, dose to volume, and volume to insulin-syringe units — with the arithmetic shown rather than hidden.
Calculators
Five working calculators covering every calculation the index performs on a record. Each one shows its arithmetic, states what it assumes, and names the index rule it would trigger. They exist so that a reader can check the site rather than believe it.
Purity to recovered mass
The calculation the index performs on every record with a peptide-content figure: from the gravimetric mass balance and the purity to how many milligrams of the named compound are actually in the vial.
Mass-accuracy and charge-state calculator
Theoretical against observed monoisotopic mass in ppm, mDa and absolute Da, plus the m/z ladder for charge states 1+ to 6+.
Impurity reconciliation checker
Paste a purity figure and a list of impurity area percentages; the checker closes the chromatogram, ranks the peaks, and tells you which index rules the certificate would trigger.
Endotoxin dose-limit calculator
The K/M calculation: from a body mass and a dose, the endotoxin concentration a material may carry, and whether a measured figure is inside it.
