Subject: cut fluorescence
Уважаемые коллеги!
Речь идет об анализе бурового шлама в лучах ультрафиолета.

Those parts of the sample exhibiting fluorescence are picked out and placed in a porcelain test plate hole to be examined for cut fluorescence.

Не могу перевести cut fluorescence.
Может, кто подскажет?
С уважением,

Возможно, для проверки на люминесценцию среза (под микроскопом)

Возможно, Вы правы.
У меня еще возникала версия измерения "спектра флюоресценции".
Но зацепиться не за что...

Fluorescence measurements can indicate the presence of aromatic compounds in petroleum and its products. Fluorescence of pyrolysis products (bitumen) is an approximate indicator of the petroleum potential of a sediment.

Most of the time, when the gas data suggest a thermogenic origin, fluorescence is measured on the bulk samples taken from each core. A small amount of sample taken from the headspace sample is placed in an aluminum pan, and a few milliliters of trichloroethane are added. The sample stays in the trichloroethane for 15-30 min, and the fluorescence intensity is estimated by the ODP operations manager or organic chemist under an ultraviolet lamp. Strong light yellow fluorescence of the sediment and a white-blue fluorescence of the fluid ("cut fluorescence") may indicate the presence of liquid hydrocarbons (Shipboard Scientific Party, 1995).
