American Polymer Standards Corporation

Providing Molecular Weight Determination Services, Polymer Standards and GPC Columns since 1983

 

American Polymer Standards Corporation is an independent contract laboratory specializing in molecular weight distribution analysis by various determination methods. Methods used are Gel Permeation Chromatography/Size Exclusion Chromatography (GPC/SEC); Multi-Angle Laser Light Scattering (MALLS) and Vapor Pressure Osmometry (VPO). We have extensive experience analyzing such materials as Nylon, Polyethylene Terephthalate, Polyurethane, Polyethylene, Polypropylene, Copolymers, etc...

As an independent laboratory APSC is committed to providing the highest quality characterization of your polymer samples. Our customers can be assured that as a independent laboratory confidentiality is a top priority with us. Expert witness services are also available.

APSC works closely with customers that require method development or that wish to have us perform analysis using the customers own method.

APSC offers a wide variety of organic and aqueous polymer standards. Polymer standards listed on this site are ideally suited for calibrating instruments and determining molecular weights of polymer samples by applications such as GPC/SEC, MALLS, VPO, etc. These polymer standards are only offered for research and investigational purposes and are not intended for Food, Drug, Cosmetic or Household use.

AM GPC Gel Columns are available in the solvent of your choice and are offered for a fraction of the price of other column producers. AM GPC Gel Columns are made of highly cross-linked ST-DVB copolymer for use with most organic solvents (e.g. DMF, NMP, DMSO, HFIP, THF, TCB etc...).

APSC offers the service of regenerating your old columns for a fraction of the cost of replacing them. In most cases we can have your columns regenerated and shipped back within 7 business days. Every regenerated column meets or exceeds new column specifications. All columns are shipped in the solvent of your choice.

Multi - Angle Laser Light Scattering (MALLS)

Determining the weight average molecular weight (Mw)of organic and water soluble polymers by MALLS is done by injecting the solution into a chromatography system with a 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.

Instrumentation: Wyatt Dawn
Molecular Weight Range:

Organic Solvent (Above 10,000 g/mol)
Aqueous Solvent (Above 10,000 g/mol)

Temperature: Room Temperature
Turnaround Time: 7 Business Days from Receipt of sample(s)
Price: $1,815.00 - First Sample
$1,210.00 - *Additional Sample(s)

*Additional Sample(s) pricing based on samples received at the same time using the same operating conditions.

Vapor Pressure Osmometry (VPO)

Determination of number average molecular weight (Mn) of organic and water soluble polymers by VPO; at a given temperature the vapor pressure of a solution is less than that of pure solvent. The solution and the solvent droplets are placed directly on two thermistors arranged in a Wheatstone bridge circuit so that the temperature rise (the solution droplet is heated up by the latent heat of condensation) can be measured very accurately as a function of the bridge imbalance output voltage.

Instrumentation: Knauer Vapor Pressure Osmometer
Molecular Weight Range: Organic Solvent (40 - 35,000 g/mol)
Aqueous Solvent (up to 10,000 g/mol
Temperature Range: Room Temperature to 130°C
Turnaround Time: 7 Business Days from Receipt of sample(s)
Price: $2,200.00 - First Sample
$1,650.00 - *Additional Sample(s)

*Additional Sample(s) pricing based on samples received at the same time using the same operating conditions.
