CCHM311 Prelim Practice

Capable of providing a single test result on approximately 40 samples per hour.

Following are not the disadvantages of automation, EXCEPT:

All samples are loaded at the same time.

One specimen with more than one test is analyzed

Able to perform individual test or panels.

System other than manufacturer's reagents can be utilized for measurement

Transports specimen quickly from one location to another

A multilayered film technology use by automated analyzers

A mechanized device that automatically dips into a sample cup and aspirates a portion of liquid.

Maximum number of test generated per hour

At least two analytical modules supported by one sample and reagent processing and delivery system

It is also known as a "run-based" system which cannot be interrupted once the batch-testing measurement has started.

Have the capability of running multiple tests one sample at a time.

Time considered for a ___ is 20 seconds to 1 minute.

Measure the total amount of analytes that participate in the reaction

Commonly utilized sample in the Clinical Chemistry Section

Lt is a special alumina-silicate glass that has been strengthened chemically than thermally; six times stronger than borosilicate.

It is utilized for high thermal, drastic heat shock, and extreme chemical treatment with acids (except hydrofluoric) and dilute alkali; it can be heated to 900°C.

Its thermal resistance is less as compared to borosilicate glass.

This type of pipette usually has the greatest degree of accuracy and precision and should be used when diluting standards, calibrators, or quality control material

It has continuous etched rings on top or near the mouthpiece of the pipette and exact volume is obtained when the last drop is blown out.

It operates by moving the piston in the pipette tip or barrel, much like a hypodermic syringe.

It relies on piston for suction creation to draw the sample into a disposable tip

calibrating medium for TD pipettes

Centrifuge calibrated every?

Produces a tightly packed, flat sediment surface.

Suitable for extreme temperature treatment (-70 °C to 200° C)

It is approved for human consumption (not injurious to individuals) but may not be applicable for laboratory analysis.

A solution in which there is an excess of undissolved solute particles

Calibrator for Centrifuge

Study of phenomenon of light adsorption by molecules in solution

Isolates light within a narrow region of the spectrum.

This utilized a flameless dehydrates and atomizes a sample using a graphite capillary surface

Distance traveled by one complete wave cycle

CUVETTE for Visible incandescent

Color transmitted by Blue

575-600nm

Emits radiation that changes in intensity

Emits limited radiation and Wavelength

Allows only a narrow fraction of the spectrum to reach the sample cuvette

Used for measurement of solution requiring visible and ultraviolet spectra

Basic photodetector for detecting and measuring radiation in the visible region

Not sensitive as PMT but with excellent linearity

Chemical reaction produces colored substance that absorbs light of a specific wavelength

With 2 photodetectors, for the sample beam and reference beam

Element is not excited by merely dissociated from its chemical bond and place in an unionized, unexcited ground state.

It is based on the fragmentation and ionization of molecules using a suitable source of energy

Measures reduction in light transmission by particles in suspension and light is measured at angle from light source

Migration of charge particles in an electric field.

Gold standard in drug testing

Has a net charge that can be either positive or negative depending on PH conditions

Is the movement of buffer ions and solvent relative to the fixed support

Migration of small ions

Separates by electrical charge

Separates proteins into 20 fractions used to study iso enzymes

It scans and quantitates electrophoretic pattern.

Very sensitive even to nanogram quantities of proteins

Ideal for separating proteins of identical sizes but with different net charges

Ideal temperatures higher than 60 degrees Celsius and react with more sample

PCO2 level in the sample is determined indirectly by sensing the pH change in this solution

Not affected by hyperproteinemia and hyperlipidemia

Measurement of the current flow produced by an oxidation reaction

Amount of increase in current proportional to the concentration of analyte

It is the measurement of current after which a potential is applied to an electrochemical cell

Separation of solute is based on relative solubility in an organic solvent and an aqueous solvent

Is based on the competition between the sample and the mobile phase for sites on the solid stationary phase.

A semiquantitative drug screening test.

Uses pressure for fast separations

What is the common source of light for the UV region

In the SI unit What is the base quantity of time?

To convert INCHES into CENTIMETERS multiply by?

To convert POUNDS into KILOGRAMS multiply by?

Instrument able to perform tests from at least two disciplines

Atleast two instrument from a single discipline with one controller
