Abstract: A method and a system for determining analyte content in a fluid in a treatment apparatus. The method comprises positioning a device for treatment in a treatment apparatus. A surface of the device is contacted with a fluid. An analyte content in the fluid is determined based on an electromagnetic property of the fluid following contacting the surface of the device with the fluid. More specifically, an electromagnetic property is measured. The measuring comprises emitting electromagnetic radiation into the fluid in the treatment apparatus and detecting electromagnetic radiation from the fluid. In another aspect, a system comprising a treatment apparatus and a detector for determining the analyte content in the fluid in the treatment apparatus is provided.

Abstract: A method and a system for adjusting a cycle time of a treatment process for an object are provided. The method comprises introducing a treatment agent comprising hydrogen peroxide into a chamber comprising the object and conducting a first treatment stage therein. A hydrogen peroxide vapor concentration in the chamber is measured utilizing a sensor during the first treatment stage to obtain a measured concentration. The measured concentration is compared to a threshold concentration value to obtain a comparison value. A cycle time of the first treatment stage is adjusted based on the comparison value.

Abstract: The present invention relates to the field of mammalian cell culture, and provides methods and compositions for cell attachment to, cultivation on and detachment from a solid substrate surface containing from at least about 0.5% N, a sum of O and N of greater than or equal to 17.2% and a contact angle of at least about 13.9 degrees, lacking a feeder cell layer and lacking an adlayer.
