Cleaning agents concentration

Once CIP systems are validated, appropriate documentation should be maintained to show that critical parameters (e.g., time, temperature, turbulence, cleaning agent concentration, rinse cycles) are achieved with each deaning cycle. 

Natural-water concentrations of boron are usually well below this value, although higher concentrations can occur as a result of industrial waste effluents or cleaning agents. 

Some clean agents may not be appropriate for all applications as they can produce materials toxic to people, especially in inerting concentrations. 

Where the clean agent is used for inerting and extinguishment, the higher of the recommended concentrations should be used. Concentration safety factors should be used as follows for ... 

The enclosure for the clean agent system should be examined for openings and tested to ensure that the agent concentration can be maintained. Currently, the preferred method is using a blower door fan unit and smoke pencil. 

Recent studies have revealed that carbon tetrachloride is also a common contaminant of indoor air. Typical concentrations in homes in several U.S. cities were about 1 pg/m (0.16 ppb), with some values up to 9 pg/m (1.4 ppb) (Wallace 1986). Concentrations in indoor air were usually higher than in outdoor air, indicating that the source of the carbon tetrachloride was building materials or products (pesticides, cleaning agents) inside the home (Wallace 1986 Wallace et al. 1987). Based on 2,120 indoor air samples in the United States, the average concentration of carbon tetrachloride was 0.4 ppb (2.6 pg/M) (Shah and Heyerdahl 1988). However, the median value was 0 ppb, indicating that carbon tetrachloride was not detected in more than half the samples. 

Chemical effect this is the influence of the chemicals in the detergents, cleaning agents or acids used. The concentration of these chemicals depends on the degree of equipment contamination.

Since tetrachloroethene is widely used as a dry-cleaning agent, foods stored close to a source of TCE, such as a dry-cleaning operation, may be exposed to atmospheric concentrations of TCE that could then be absorbed by the food. TCE was found in butter and lard bought from shops close to dry cleaners, at concentrations up to 763 /xg/kg.67 Residues of 1,1,1-trichloroethane, chloroform and trichlorofluoromethane were also found in some samples of butter and lard, although at much lower concentrations than the TCE. 

Several preanalytical factors can cause a false elevation of the measured plasma ammonium concentration. These include prolonged tourniquet application, hemolysis, specimen transportation at room temperature, delay in plasma separation, and even ambient ammonium from cleaning agents or cigarette smoke. These fac-... 

Sodium hydroxide is widely used in the biotech industry to both regenerate and sanitize chromatography resins to a certain extent. The practice of using sodium hydroxide as a cleaning agent varies a lot in terms of concentration (0.1 to 1 N), incubation times (hours to several days), temperature, and column volumes passed through the column (1 to more than 10).
