In embodiments, the ECL co-reactant is triethanolamine (TEA), tert-butyldiethanolamine (tBDEA), methyldibutylethanolamine (MDEA), 3-[Bis-(2-hydroxy-ethyl)-amino]-propane-1-sulfonic acid (DEA-PS), or a combination thereof. Methods of using the compositions and kits comprising the compositions are also provided herein. | 2022-01-20 |
20220018786 | MEASURING DEFLECTION TO DETERMINE A CHARACTERISTIC OF A CANTILEVER - Disclosed are methods that, by not physically touching a material being measured, can measure the material's differential response quite accurately. A collimated light shines on the material under test, is reflected off it, and is then captured by a device that records the position where the reflected light is captured. This process is done both before and after the material is processed in some way (e.g., by applying a coat of paint). The change in position where the reflected light is captured is used in calculating the deflection of the material as induced b the process. This measured induced deflection is then used to accurately determinate the stress introduced into the material by the process. Other characteristics of the material under test, such as aspects of the material composition of a bi-metallic strip, for example, may also be determined from a deflection measurement. | 2022-01-20 |
