Chapter 6 And 7 Flashcards
Qualitative and quantitative
Analyzer measurements
A graphic record of the separated components
Chromatogram
A process where molecular components of a liquid or gas are separated and identified by means of a tube called a column
Chromatography
A photometer that operates in the visible light spectrum (400-800 mu) two types include either the visual color analyzer and the photometer or a spectral color analyzer
Color/optical analyzer
The rapid consumption of fuel resulting in its conversion to heat , light and gases.
Combustion
A measurement of the ability of a material to conduct electrical current . The measure of of the ability of a liquid (or any solution) to conduct electricity
Conductivity
A device that measures all ions in an aqueous solution
Conductivity analyzer
A device that measures the conductivity of a process sanple by comparing it to a known value or standard cell
Conductivity meter
A nonmetallic substance that is an ionic conductor, the greater a substance conducts an electrical charge , the more ionic substance becomes
Electrolyte
An analyzer that provides the necessary means to accomplish the chromatographic separation and analysis.
Gas chromatographic analyzer
An anallytical method that can provide a molecular separation of one or more individual components in a sample
Gas chromatography (GC)
An analyzer ( either continuous or contiguous) installed directly in a process line that may be either a sample system of separating a gaseous stream into a spectrum according to mass and charge
Mass spectrometer (MS)
An optical analyzer used to determine how much particulate matter is in a gas sample
Opacity analyzer
A measurement that uses reflection,refraction, or absorbtion properties of light to measure the chemical or physical properties of a sample
Optical measurement
Any or all the following: turbidity meters,opacity meters, and color meters
Optical meters
An electrochemical analyzer that measures a small electro motive force across a hydrogen-ion sensitive glass bulb ; an (ORP)oxidation reduction potential meter also measures a small voltage across its electrode and I has the capability of detecting all oxidizing and reducing ions in the solution
ORP analyzer
A measure of redox potential created by the ratio of reducing agents to oxidizing agents present in this
Oxidation reduction potential (ORP)
A measurement of the hydrogen ion concentration will be solution indicating acidic below 7.0 or basic above 7.0 a substance is from neutral 7.0
Ph
And electro chemical instrument that measures the acidity and alkalinity of a solution, an analyzer that measures a specific ion ( hydrogen ) concentration in a solution
Ph meter
A color analyzer that operates in the visible light spectrum 400–800 UM
Photometer
Automated system used to determine the color of a sample
Photometry system
An unattended analytical instrument that is capable of continuously monitoring a process stream
Process analyzer
Characteristics of a substance such as pH, ORp,conductivity, optical measurement, composition, and or combustion capability
Properties
Measurement of the properties of a substance
Qualitative
A measurement of the amount of properties within a substance
Quantitative
A sample that contains portions of the process stream combined together over time or distance
Representative sample
The various components of a sampling apparatus that obtains transports, and returns the sample with the analyzer itself conditioning and analyzing the sample
Sample system
A graph where transmittance is plotted with respect to wavelength
Spectrograph
An analyzer used to detect chemical components in a process sample by measuring variations in transmittance in a process sample; of a spectrum of light passed through the sample may use visible lights ultraviolet light, or infrared light as a source and detection measurement
Spectrometer analyzer
In analyzer used to determine how much Carbon is in a sample, used to detect carbon – based contaminants in steam condensate and waste water
Total carbon analyzer
An optical analyzer used to determine the cloudiness of a liquid
Turbidity analyzer
Optical meters measure the transmittance or absorption of light through a sample
Turbidity and opacity meters
Compares a physical sample with a standard by shining visible light through the sample and the color comparison is made by the human eye/brain
Visual color analyzer
A vibration Measuring device
Accelerometer
The operating range within which a piece of rotating equipment can operate without causing excessive wear to the bearings, or other types of catastrophic failure
Acceptable limits
Where a solid material is weighed as it is conveyed on a moving belt and an instantaneous weight measurement is taken and the rate of motion of the belt is known
Mass flow rate
A dangerous condition that can occur in a turbine or other type of equipment that moves too fast
Overspeed
Linear speed expressed in distance per unit of time
Rectilinear speed
Number of revolutions per unit of time
Rotational speed
The distance traveled per unit of time irrespective of direction
Speed
A device that measures speed, comprised of a speed sensor and the readout/receiving device
Speed monitor
Speed with a specific direction
Velocity
The periodic motion of an object
Vibration
A device used to measure displacement, velocity, or acceleration due to vibration, consist of a pick up device, and electronic application circuit, and an output meter
Vibration meter
A device used to sense the effects of vibration by a signal to a meter or monitor, or to shut down a device if operating limits are exceeded
Vibration sensors or monitors
