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. |

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. |
|

|
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)普魯蘭混標使用說明: |
|
|
|
|
|
|
|
|
1.選擇對應的分子量混標小瓶并打開; |
|
|
|
|
|
|
|
|
2.用注射器或移液管向瓶中加入適量的溶劑 |
|
|
|
注:當使用粘度計或光散射檢測器時,精確稱量所需添加溶劑的量,計算出樣品濃度 |
|
|
|
|
|
|
3.擰緊瓶蓋等待2-5小時;可以輕搖瓶子使其混合均勻 |
|
|
|
注:在此期間輕搖小瓶可加速溶解過程 |
|
|
|
|
|
|
|
|
4.將混標溶液加入儀器測試,用Mp值構建校準曲線。 |

注意: |
|
|
|
|
溶液盡量現配現用,最多保存2天。已配溶液只能短時間放在冰箱(2-8℃),切勿冷凍標準溶液,否則樣品受損。 |
