English term or phrase: match quality
The peak purity degree was evaluated according to the following procedure: two spectra for each sample was taken into consideration (at the peak apex and at apex + 0.25 minutes of the peak retention time- this value of retention time corresponds to the 99% of the total peak area) and compared with the respectively taken spectra on a reference solution of Memantine Hydrochloride at the method concentration that were stored in the system library as reference spectra.
Results were expressed in terms of “match quality”, i.e. a grade of comparison and superposition of two spectra.
All the purity results were referred to the one obtained injecting a test solution.
At the same time, to make the comparison of the results even easier, a value of assumed purity % for each analysis was calculated as:
Match quality sample
Assumed Purity % = -------------------------- x 100
Match quality freshly prepared solution
A match quality of 90% was considered acceptable as purity index.

Вот пример употребления (там правда, исходный английский термин другой, но смысл тот же):

В ка­чес­тве до­пол­ни­тель­ных кри­тери­ев спе­цифич­ности ис­поль­зо­вали спек­траль­ную чис­то­ту (спек­траль­ную од­но­род­ность) пи­ков гид­рохло­роти­ази­да и пен­токси­фил­ли­на (при­ем­ле­мой яв­ля­лась спек­траль­ная чис­то­та пи­ков не ме­нее 900) и сте­пень сов­па­дения («match factor») спек­тров оп­ре­деля­емых ве­ществ в мо­дель­ных и ис­пы­ту­емых рас­тво­рах (не ме­нее 950).
