Concentration and Efficiency of Disinfectants
The more concentrated the disinfectant, the higher its effectiveness, and the shorter the time required for microbial destruction. It is also essential to consider the duration of the disinfection process, which depends on the bactericidal effectiveness.
Procedure
The control of the concentration of working disinfectant solutions is a multi-stage process characterized by the examination of the active substance content in a liquid, multi-component system. The express method involves taking samples in laboratory conditions, and the analysis is carried out using test strips (indicators) that provide accurate results.
The concentration control of disinfectant solutions is carried out using modern equipment, analytical, and physico-chemical processes. After verification and determination, you obtain precise results.
System equipment allows for the most accurate determination of the concentration of active components in the environment. This rule directly impacts the execution of disinfection procedures and enables the timely prevention of contamination by pathogenic microorganisms on the object.
Test strips for dilution are used in laboratories to determine the effectiveness of a chemical disinfectant. To do this, the test strip is immersed in the culture of the target microorganism and then dried. Subsequently, the test strip is dipped into the disinfectant solution at various concentrations for a specified time. In the final stage, the test strip is transferred to another test tube containing fresh sterile medium without the disinfectant, and this tube is incubated. Bacterial survival is demonstrated by the presence of cloudiness in the medium, whereas killing the target organism in the test with the disinfectant will not result in cloudiness.
Purpose of Concentration Control of Working Disinfectant Solutions
Compliance with the established norms and rules regarding the level of active substance in the disinfectant corresponds to the conditions of sanitary requirements set by the Sanitary and Epidemiological Surveillance. Inspection organizations are interested in adhering to the normative indicators of working preparations, with their task being to account for the percentage ratio of the active substance to the total mass of solutions.
The concentration control procedure for disinfectants is used for releasing medical products to pharmacies or medical institutions where it is necessary to determine the clear ratio of the solution’s concentration. In cases where it is impossible to independently determine the concentration, we recommend seeking professional assistance. If your facility lacks the capability to independently determine the concentration, we suggest using specialized help.
We possess the appropriate certificates and licenses to provide services. After conducting the analysis, documents confirming compliance with normative indicators are handed to the customer. These papers have legal force, validated by the seals and stamps of the organization and laboratory. Our experts conduct a quick analysis and document the findings in accordance with Federal Laws.
