CT Value definition

CT Value means a representation of the concentration of the disinfectant (C) multiplied by time in minutes (T) needed for inactivation of a particular contaminant. The concentration and time are inversely proportional; therefore, the higher the concentration of the disinfectant, the shorter the contact time required for inactivation. The CT value can vary with pH or temperature change so these values must also be supplied to allow comparison between values.

CT Value means the contact time multiplied by the free disinfectant residual required to achieve adequate disinfection.

CT Value means a representation of the concentration of the disinfectant (C) multiplied by time in minutes (T) needed for inactivation of a particular contaminant. The concentration and time are inversely proportional; therefore, the higher the concentration of the disinfectant, the shorter the contact time required for inactivation.

Examples of CT Value in a sentence

• An antibody test and a new PCR shall be performed.If the antibody test is positive and the CT value of the second PCR is the same as the 1st PCR, then the person shall remain in quarantine and a new PCR shall be repeated 5 days later.After 5 days if CT Value is > 35, please see below.

• The CT Value is exponential, and so a 40-cycle threshold means that the sample is magnified around a trillion times.

• The higher the CT Value, the less likely the detected fragment of viral RNA is intact, alive and infectious.5Virtually all scientists, including Dr. Fauci, agree that any PCR test run at a CT value of 35-cycles or greater is useless.

• Rolling stock is tired and there is high dependency on car usage.

• Reduction of dental metallic artefacts in CT: Value of a newly developed algorithm for metal artefact reduction (O-MAR).

• George CF, Breckenridge AM, Dollery CT: Value of routine electrocardiography in hyper- tensive patients.

• Temperature (ºC)Rate (g/m3) Minimum Concentration Readings (g/m3) at: C/T Value* (g h/m3)0.5 hr*C/T values are calculated based on time decay rates experienced under tarpaulin.

• The analysis should include a list of requirements for a replacement portfolio that diversifies and improves the resilience and maintains the reliability and adequacy of the electric power system, is consistent with the state's statutory and regulatory requirements for clean electricity generation, and is supplementary to the resources that will be required to replace fossil fuels in the electrical generation, transportation, industry, and buildings sectors.

• For εACC and εTB, the grid ranged from .001 to .999, to avoid extreme values of the likelihood being zero or one, respectively.

• Multiple sampling ports shall be provided to enable sampling of each compartment'seffluent water and to confirm CT Value calculations.

More Definitions of CT Value

CT Value means a representation of the concentration of the disinfectant (C) multiplied by time in minutes (T) needed for inactivation of a particular contaminant.

CT Value means the product of the disinfectant contact time (T) in minutes and the concentration of the disinfectant residual (C) in mg/L measured at the end of the contact time. The product of these two parameters (CT) provides a measure of the degree of inactivation of specific organisms.

CT Value means the product of disinfectant residual and disinfectant CT. The required amount of CT needed is contained in the EPA Guidance Manual to the Surface Water Treatment Rule.

CT Value. In fumigation methods a dose is expressed by the CT value which is the product of concentration and time. Coating: A coating is a covering that is applied to the surface of an object. A coating may be applied to improve cleanability. Coatings may contain antimicrobial agents that can inhibit microbial growth or kill microbes through a variety of means, including biocidal agents or nanoparticles. Disinfection: Disinfection is a process that eliminates most pathogenic microorganisms, except bacterial spores, on inanimate objects (Rutala et al., 2017). This can be achieved by applying chemicals (i.e. disinfectants, a type of antimicrobial) to surfaces or liquids that harbour these organisms or by using physical processes such as heat. Decontamination: Decontamination is making an object or area safe by removing, neutralizing, or destroying harmful substances, such as microbes, toxic chemicals or radioactive material to the extent necessary to prevent the occurrence of adverse health effects. Decontamination can be a combination of processes (one of which is disinfection, another is sterilisation). There are differences between disinfection and decontamination. Decontamination is often related to security and may involve much stronger means of cleaning than disinfection – it may be so strong that it poses a health threat and may require sealing or isolation of the cleaned space. This implies that decontamination is conducted by experts while disinfection using milder methods can be carried out routinely by regular staff. Microbe: A microbe is a microscopic organism (the term is interchangeable with the term microorganism), which may be useful, harmless or harmful. In this context the focus is on microorganisms that can cause infection in humans. This report focuses on bacteria and viruses, not fungi, prions, yeasts, protozoa and helminths. Sterilisation: Sterilisation is a decontamination process that completely inactivates all living organisms, including spores (Pottage et al., 2015). Sterilisation methods may be chemical or physical.
