Condenser microphones are the most common types of microphones you'll find in studios. They have a much greater frequency response and transient response - which is the ability to reproduce the speed of an instrument or voice.
protein-bound iodine test n. A test to determine thyroid function in which serum protein-bound iodine is measured. The American HeritageÂ® Stedman's Medical Dictionary
The Iodine test is used to test for the presence of starch. Iodine solution â iodine dissolved in an aqueous solution of potassium iodide â reacts with the starch, producing a purple-black colour. The colour can be detected visually with concentrations of iodine as low as 0.00002 M at 20 Â°C. However, the intensity of the color decreases with increasing temperature and with the presence of water-miscible organic solvents, such as ethanol.
