The ion source converts and fragments the neutral sample molecules into gas-phase ions that are sent to the mass analyzer. While the mass analyzer applies the electric and magnetic fields to sort the ions by their masses, the detector measures and amplifies the ion current to calculate the abundances of each mass-resolved ion.
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.
Quality control begins with sample collection and ends with the reporting of data. [4] 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.
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.
It’s tamale time. This Mexican comfort food has a long history and is an essential part of every major holiday, particularly Christmas. It’s also the perfect portable snack for holiday travelers.
The wholesale price report comes a day after the government reported that consumer prices rose 2.7% in November from a year earlier, up from an annual gain of 2.6% in October. The increase, fueled ...
The New York Mets (Port St. Lucie, Fla.) will have their pitchers and catchers report on Monday, Feb. 12. Other clubs are expected to have their pitchers and catchers in camp by Feb. 14.
The analysis of results is performed by determining the ratio of elements from within the sample and working out a chemical formula that fits with those results. This process is useful as it helps determine if a sample sent is the desired compound and confirms the purity of a compound.
