An LCR meter is a type of electronic test equipment used to measure the inductance (L), capacitance (C), and resistance (R) of an electronic component. [1] In the simpler versions of this instrument the impedance was measured internally and converted for display to the corresponding capacitance or inductance value.
Laboratory quality control is designed to detect, reduce, and correct deficiencies in a laboratory's internal analytical process prior to the release of patient results, in order to improve the quality of the results reported by the laboratory.
Hazardous chemicals present physical and/or health threats to workers in clinical, industrial, and academic laboratories. Laboratory chemicals include cancer-causing agents (carcinogens), toxins (e.g., those affecting the liver, kidney, and nervous system), irritants, corrosives, sensitizers, as well as agents that act on the blood system or damage the lungs, skin, eyes, or mucous membranes.
AQC is achieved through laboratory control of analytical performance. Initial control of the complete system can be achieved through specification of laboratory services, instrumentation, glassware, reagents, solvents, and gases. However, evaluation of daily performance must be documented to ensure continual production of valid data.

The FDA requires nonclinical laboratory studies on new drugs, food additives, and chemicals to assess their safety and potential effectiveness in humans in compliance with 21 CFR Part 58, Good Laboratory Practice for Nonclinical Studies under the Federal Food Drug and Cosmetic Act and Public Health Service Act.

Chemical Safety Reports are the main end point for data assessment under REACH (the European Community Regulation on chemicals and their safe use, concerning the Registration, Evaluation, Authorisation and Restriction of Chemical substances [4]) in which hazard and exposure data are considered together to assess the risk of a substance.

The Occupational Safety and Health Administration (OSHA) in the United States established the allowed exposure limit for occupational noise at 90 dB and is based on an 8-hour time-weighted average for an 8-hour workday. [16] For worker's safety, OSHA mandates hearing conservation programs when noise levels are higher than 85 decibels. [17]
