ZZSTANDARD Pullulan mixtures are the easiest way to perform GPC/SEC calibrations. Use Pullulan mixture to obtain fast, precise and reproducible calibrations. The exact weight in the vial is known allowing the concentration to be altered by varying the amount of added eluent.

Advantages

Applicability

Fast

Conventional calibration

Reliable

Universal calibration

Easy and safe handing

Instrument validation

Free of contamination

Calibration of detectors

Tip: if you use an internal flow market,please add it directly to the solvent used to prepare the Pullulan mixtures solutions.

How to use Pullulan mixtures:

1.Select the appropriate vial and unscrew the cap

2. Add the correct volume of solvent via syringe or pipette etc

Tip: When viscometer or light scattering detectors are used weigh out the added amount of solvent precisely to calculate the concentration.

3.Screw on the vial cap and wait for 2-5 hours. Gently swirl the vial to homogenize.

Tip: Slightly shaking the vial during this time will speed up the dissolution process.

4.Inject each solution separately and use Mp values to construct a calibration curve.

Note:

Solutions

Use only freshly prepared solutions and use them up within two days.Solutions may only be stored in the refrigerator temporarily for a short time period.Do not freeze the standard solutions,freezing can destroy the sample.
