Determination of Weight Average Molecular Weight of Organic and Water Soluble Polymers by MALLS
(Multi-Angle Laser Light Scattering)

Instrumentation: Wyatt Dawn

Principle of Operation:
A solution is injected into a chromatography system with the MALLS instrument and a refractometer.
The intensity of the scattered light is proportional to the molecular weight.
The weight average can be calculated using a known dn/dc value, a specific refractive index
increment of the solute-solvent mixture and a known concentration

Molecular Weight Range:	Organic Solvent (Above 15,000 g/mol)
	Aqueous Solvent (Above 15,000 g/mol)

Temperature Range: Room Temperature

Turnaround Time: Seven (7) Working Days

Price:	$1,650.00 for the first sample
	$1,100.00 for each additional sample

For samples received at the same time and using the same operating conditions
