Limits for NVPC at rest and in operation refer to the non-viable particle count in a cleanroom environment.

• NVPC limits are typically specified in particles per cubic meter (e.g. 3520 particles/m3 at rest, 35200 particles/m3 in operation)

• These limits are important for maintaining cleanliness and quality in pharmaceutical or semiconductor manufacturing facilities

• Regular monitoring and testing of NVPC levels is necessary ...read more

Molarity and molality are two different ways of expressing the concentration of a solution.

• Molarity is the number of moles of solute per liter of solution.

• Molality is the number of moles of solute per kilogram of solvent.

• Molarity changes with temperature, while molality does not.

• For example, a 1 M solution of NaCl contains 1 mole of NaCl per liter of solution, while a 1 molal solution of NaCl contains 1 mole of NaCl pe...read more
