German term

gegen Abzug

German to English Science Chemistry; Chem Sci/Eng spectroscopy
Die Spektrenaufnahme erfolgte durch Aufbringen der im NMR-Teil verwendeten Lösungen auf KBr-Leerpresslinge (Herstellung siehe 13.3.4) und Verdampfen des Lösemittels bei Raumtemperatur. Es wurden unterschiedliche Volumina zwischen 20 μl und 90 μl verwendet. Vom verbleibenden Film wurde ein Transmissions- Spektrum aufgezeichnet. Zur Spektrenaufnahme wurde ein Fourier-Transform-Infrarot-Spektrometer mit nachfolgender Spezifikation und Messparametern verwendet.

Jede Probenmessung erfolgte ***gegen Abzug*** des spektralen Hintergrundes (ratio-mode), der alle 2h erneut aufgenommen wurde.

involved filtering out

Each analysis involved filtering out (subtracting) the spectral background.

agree David Hollywood : either option would work IMO

Thanks, David. The second of these seems to have attracted approval elsewhere on the page.
agree rainerc (X) : With David.

agree Yorkshireman : This is the term we used when extracting background noise from spectra in seismic processing to get at the reflection signals. As Andrew also says in his explanation, subtracting (subtraction) is a very good description of the process.

against penalty

Abzug bedeutet"Penalty" bei Stichprobeprüfungen. Ich bin mir sicher. Aber wie es hier passt ist mir nicht ganz klar. Vielleicht wird das so verwendet.

Pls check Langenscheidt Tech Dict.. It is clearly stated there that Abzug means penalty in this context. It is an authentic dictionary.
disagree Carola Lange : dies ist keine Stichprobenpruefung, they are talking about a specific number of Proben / samples

subtraction

Infrared spectra were obtained using a Perkin-Elmer Model 1600 fourier transform infrared spectrometer. The optical system consists of a 633 nm helium-neon laser (intensity < .3 mW) and a lithium tantalate (LITA) detector. Spectra were recorded as an accumulation of 64 scans taken in ratio mode to permit subtraction of existing background spectra.
