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.
（中文版）普鲁兰混标使用说明：
1.选择对应的分子量混标小瓶并打开；
2.用注射器或移液管向瓶中加入适量的溶剂
注：当使用粘度计或光散射检测器时，精确称量所需添加溶剂的量，计算出样品浓度
3.拧紧瓶盖等待2-5小时；可以轻摇瓶子使其混合均匀
注：在此期间轻摇小瓶可加速溶解过程
4.将混标溶液加入仪器测试，用Mp值构建校准曲线。
注意：
溶液尽量现配现用，最多保存2天。已配溶液只能短时间放在冰箱(2-8℃),切勿冷冻标准溶液，否则样品受损。
