Detection limit

Detection limit CC6

the limit of detection of the proposed methods;

The detection limit for the method is 0,01 mg/kg.

the limit of detection and determination of the proposed methods for impurities.

The limit of detection must be 20 %.

The limit of detection can be calculated using different approaches:

The limit of detection of the test is 30 mg of salicylic acid per 100 g of sample.

The limit of detection of this test is 30 mg of formaldehyde per 100 g of sample.

The limit of detection for reducing substances reacting is 100 mg glucose per 100 g of sample.

The detection limit of sulphur dioxide in 10 ml of TCM sampling solution is between 0 72 and 1 70 ¶g (based on twice the standard deviation).

The limit of detection is calculated as the apparent content corresponding to the value of the mean plus three times the standard deviation for the blank determinations.

This testing shall include closely related events, where relevant, and cases where the limits of the detection are truly tested.

If such a method does not currently exist, an analytical method with appropriate performance characteristics at the specified limit may be used, pending the development of a validated method;";

Other methods may be used provided that the limits of detection, precision and accuracy of such methods are at least as good as those laid down in Annex III (1) to Directive 82/176/EEC.

The measuring range of the method is determined by the limit of detection of the analytical procedure.

For diode array detection, this is typically within ± 2 nm.

For diode array detection, this is typically within ± 2 nm.

The limit of detection may be set as 3 x the standard deviation of the solvent blank or of the background response.

I n the case of substances for which no permitted limit has been established, CCΓΆ can be established by:

I n the case of substances for which no permitted limit has been established, CCβ can be established by:

A population of approximately 103 cells per ml of resuspended pellet is considered to be the limit of detection for the IF test,

The value of the decision limit plus 1, 64 times the corresponding standard deviation equals the detection capability (ΓΆ = 5 %).

The value of the decision limit plus 1, 64 times the corresponding standard deviation equals the detection capability (β = 5 %).

When working at or near the detection limit, the most sensitive line for the respective analyte is usually the best choice.

(3) The Scientific Committee on Food concluded in its opinion of 6 May 2002 that the presence of ethylene oxide should be brought below the detection limit.

The value of the decision limit plus 1, 64 times the standard deviation of the within-laboratory reproducibility of the measured co ntent equals the detection capability (ΓΆ = 5 %),

The value of the decision limit plus 1, 64 times the standard deviation of the within-laboratory reproducibility of the measured co ntent equals the detection capability (β = 5 %),

The corresponding concentration at the value of the decision limit plus 1, 64 times the standard deviation of the within-labora tory reproducibility equals the detection capability (ΓΆ = 5 %),

The corresponding concentration at the value of the decision limit plus 1, 64 times the standard deviation of the within-labora tory reproducibility equals the detection capability (β = 5 %),

The corresponding concentration at the decision limit plus 1, 64 times the standard deviation of the within-laboratory reproducibility o f the mean measured content at the decision limit equals the detection capability (ΓΆ = 5 %),

The corresponding concentration at the decision limit plus 1, 64 times the standard deviation of the within-laboratory reproducibility o f the mean measured content at the decision limit equals the detection capability (β = 5 %),

The absorption maxima in the spectrum of the analyte shall be at the same wavelengths as those of the calibration standard within a margin determined by the resolution of the detection system.

where no quantitative results are available, the detection capability can be determined by the investigation of fortified blank material at and above the decision limit.

If such a method does not currently exist, an analytical method with appropriate performance characteristics at the specified limit may be used, pending the development of a validated method;

extraction as appropriate, derivatisation with acetic anhydride, determination by capillary gas-liquid chromatography with electron capture detection, limit value 0,05 ppm.

Complete digestion, background measurements, appropriate choice of analytical masses sometimes associated with a lower abundance (poorer detection limit) and of dissolution acids, e. g. nitric acid, are required to avoid interferences.

Detection limit: 0,1 mg of quinine.

HBV-DNA was measured by the COBAS AMPLICOR™ HBV MONITOR Assay (limit of detection 200 copies/ ml).

The technical limit of detection of this method is situated between 103 and 104 cells per ml of undiluted pellet.

For the purposes of determining vinyl chloride released by materials and articles to foodstuffs, the detection limit shall be 0 701 mg/kg.

For substances which are not authorized for use in food-producing animals, the limit of detection should be as low as possible.

Virological response was defined as undetectable HCV RNA as measured by the COBAS AMPLICOR™ HCV Test, version 2.0

20 Overall, approximately 36 % (821/2,286) of patients had undetectable plasma HCV-RNA levels at Week 12 of therapy measured using a research-based test (limit of detection 125 IU/ml).

Overall, approximately 36 % (821/ 2,286) of patients had undetectable plasma HCV-RNA levels at Week 12 of therapy measured using a research-based test (limit of detection 125 IU/ ml).

alternatively, in the case of spectrometric determinations in which representative blank determinations give white noise only, the limit of detection is calculated as the apparent content corresponding to three times the peak-to-peak noise.
