Chemistry Definition

Medical Laboratory Science Study Guide Chem Definitions

Electromagnetic Radiation Has wave-like and particle-like properties.
Radiant Energy Characterized as a spectrum from short wavelengths to long wavelengths
Wave Length The distance traveled by one complete wave cycle measured in nanometers.
Nephelometry The measurement of light scattered by a particulate solution.
Turbidometry Measures the light blocked as a decrease in the light transmitted through the solution.
Fluorescence A process where atoms absorb energy at a particular wavelength, and the electrons release energy as they return to ground state by emitting light energy of a longer wavelength and lower energy than the exciting wavelength.
Phosphorescence The emission of light produced by certain substances after they absorb energy.
Chemiluminescence The process where the chemical energy of a reaction produces excited atoms, and upon electron return to ground state, photons of light are emitted.
Bioluminescence The process where an enzyme-catalyzed chemical reaction produces light emission.
Luminometer A generic term for the type instrument that is used to measure chemiluminescence and bioluminescence
Chromatography A technique where solutes in a sample are separated based on physical differences that allow their differential distribution between a mobile and stationary phase.
Mass Spectrometer An instrument that uses the principle of charged particles moving through a magnetic or electric field, with ions being separated from other charged particles according to their mass to charge ratio.
Potentiometry Technique used to determine the concentration of a substance in solution employing an electrochemical cell that consists of two half-cells, where the potential difference between an indicator electrode and a reference electrode is measured.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
