Cell cleaning

In chlorate production the EMOS system has also been used to determine the formation of deposits on the electrodes, either the anode or cathode and combined with the information on process and electrolyte composition the system determines the need for cell cleaning or acid rinsing. The close monitoring of individual cell voltages has allowed plant engineers to establish the most appropriate current density for production lines dependent upon the state of the anode coatings. This allows for the same overall production capacity while permitting the operation of two different cell lines in the cell room at different current densities based upon the state of the anodes and cathodes in the cell. 

THC is fat soluble, and it gets stored in your fat cells. Cleaning it out of your lipid tissue is very difficult. Many herbal products claim to clean out your system, yet they do nothing to remove THC byproducts from fat cells. A study was done in Germany in 1993 on 50 of the most common herbs used by people trying to pass the test. All 50 herbs failed to cause a negative.

Note that calculation of the absolute heat capacity requires two scans one of buffer vs buffer and one of protein vs buffer. The buffer scan is usually the scan of buffer collected immediately prior to loading the protein. The two must be highly reproducible for the result to be meaningful. Attention must be paid to cell cleaning, preconditioning, and sample loading.

Dry autopsy a complex set of actions to investigate the reasons for shutdown of the cell. This includes investigating the surface of the cell, cleaned of electrolyte and aluminium, digging trenches in the lining in chosen parts of the cell, and examining the condition of the lining and the lining materials.
