METHODS FOR MEASURING AND QUANTIFYING SURFACE CLEANABILITY OF ARTICLES

Disclosed are methods for quantifying the cleanability of a surface of an article, for instance an aircraft interior component. In embodiments, a solution containing an artificial “dirt” is introduced to a surface under test to simulate a sullied condition. The sullied surface is subjected to at least one cleaning process. Obtained reference and post-cleaning light measurements are compared to determine a measurement difference corresponding to a cleanability of the surface and/or effectiveness of the at least one cleaning process. In embodiments, the measurement difference is assigned a cleanability score for at least one of determining a passing or failing cleanability, modifying the cleaning process, indicating the need for a second or subsequent cleaning, modifying the barrier coating formulation, redesigning the article, etc. The disclosed methods provide solutions for objective verification measures of surface cleanability used to facilitate new article designs, materials, barrier coatings, cleaning processes, cleaners, etc.

AUTOMATED CONTROL OF CELL CULTURE USING RAMAN SPECTROSCOPY

The monitoring and control of bioprocesses is provided. The present disclosure provides the ability to generate generic calibration models, independent of cell line, using inline Raman probes to monitor changes in glucose, lactate, glutamate, ammonium, viable cell concentration (VCC), total cell concentration (TCC) and product concentration. Calibration models were developed from cell culture using two different CHOK1SV GS-KO™ cell lines producing different monoclonal antibodies (mAbs).
