analyte

The accuracy and precision with which known concentrations of analyte in biological matrix can be determined should be demonstrated.

How much material is available for the analysis, and what is the approximate concentration ot the compound of interest (the analyte)?

It is not always possible to demonstrate that an analytical procedure is specific for a particular analyte (complete discrimination).

Such a sensor can be used to provide a visible image that changes or appears to the eye in response to an analyte.

The detection limit is usually expressed as the concentration of analyte (e. g. percentage parts per billion) in the sample.

It should be established initially by visual examination of a plot of signals as a function of analyte concentration of content.

Since analyte atoms are excited by the heat of the flame, no special elemental lamps to shine into the flame are needed.

In a titration, the test substance (analyte) reacts with a reagent added as a solution of known concentration.

Stock solutions of the analyte for stability evaluation should be prepared in an appropriate solvent at known concentrations.

As with chromatographic methods, microbiological and ligand-binding assays should be shown to be selective for the analyte.

A transdermal test sensor assembly adapted to determine an analyte concentration of a fluid sample is disclosed.

A higher temperature flame than atomic absorption spectroscopy (AA) is typically used to produce excitation of analyte atoms.

The analyte should have no interference from other extraneous components and be well resolved from them.

Titrimetry (volumetry) is a quantitative method using solution chemistry to determine the concentration of analyte.

A highly sensitive chromatographic system is desirable particularly for monitoring analyte present in trace concentrations within samples.

In AA, the amount of light absorbed after going through the flame determines the amount of analyte in the sample.

As long as the concentration of standard is known , the correct concentration of analyte can be derived.

For compounds with potentially labile metabolites, the stability of analyte in matrix from dosed subjects (or species) should be confirmed.

For selectivity, there should be evidence that the substance being quantified is the intended analyte.

The device further comprises a processing feature adapted to inhibit the stored analyte concentrations from being displayed on the display.

A method for measuring an analyte in a sample by using a redox reaction is provided, which gives values with excellent reliability.

The quantitation limit is expressed as the concentration of analyte (e. g. percentage parts per billion) in the sample.

Paracetanol was used as the internal standard. The analyte and internal standard were extracted from plasma using liquid-liquid extraction.

If the standard only requires strength index, and shall require the analyte in what state is measured, half in detection cannot strictly.

Thus limit tests merely substantiate that the amount of analyte is above or below a certain level.

The system for detecting blood analyte concentration may include a photoacoustic device or a metabolic heat conformation device.

Then, the redox current of the indicator could reflect the concentration of the analyte.

The device further comprises a memory adapted to store a plurality of stored analyte concentrations.

Analyte stability should be determined after three freeze and thaw cycles.

The procedure should also include an evaluation of analyte stability in stock solution.

An optical signal is produced in response to an analyte placed on the chemical layer.

A color signal can be read within 10 min, and the intensity determines the amount of analyte.

The primary analyte was sensitive to mobile phase aging of the column .

The minimum concentration at which the analyte can reliably be quantified is established.

Samples involving multiple analytes should not be rejected based on the data from one analyte failing the acceptance criteria.

In geochemical analysis we encounter ranges of analyte concentration that can span several orders of magnitude.

and thereby measuring an amount of said analyte in the measured sample.

Performing analyte extraction on-site is accomplished with the CUSDT solid phase microextraction (SPME)syringe.

All three methods gave no significant loss of total glucosinolate analyte contents over these cooking periods.

Do I have to submit results for every analyte in a proficiency test ?

Estradiol is classified as a "type A" analyte by the WHO because it is a chemically well-defined compound (6).

SPR can not only be used in analyte detection, but also can determinate kinetic parameters of the molecular interaction.

Spike recovery data do not necessarily reveal the true recovery of the analyte from the sample

The method responds primarily to the analyte of interest and is little affected by other substances
