MOLAR MASS – The molar mass is the mass, expressed in grams, of 1 mole of a specific substance.
Conversely, one mole is the amount of the substance needed for the molar mass to be the same number in
grams as the atomic mass of that substance.
EXAMPLE: The atomic weight of Carbon is 12 therefore the molar mass of Carbon is 12 grams.
Conversely, one mole of carbon equals the amount of carbon atoms that weighs 12 grams.
Atomic weights can be found on any Periodic Table of Elements.
PCA – Acronym for Printed Circuit Assembly, the  PCB with electronic components, ready to use.
PCB – Acronym for Printed Circuit Board, the bare board without electronic components.
PLC – Acronym for Programmable Logic Controller, a device that is used to control instruments based on a logic
level signal coming from the analyzer.
PFA – Acronym for Per-Fluoro-Alkoxy, an inert polymer. One of the polymers that du Pont markets as Teflon
®
(along with FEP and PTFE).
PMT – Photo Multiplier Tube – a vacuum tube of electrodes that multiply electrons that are collected and
charged to create a detectable current signal.
PTFE – Acronym for Poly-Tetra-Fluoro-Ethylene, a very inert poly
mer mate
rial used to handle gases that may
react on other surfaces. One of the polymers that du Pont markets as Teflon
®
(along with FEP and
PFA).
