◆主要特點
通過兩個高靈敏度的電熱調(diào)節(jié)器測量溫差變化
通過惠斯通電橋顯示溫差變化
測量系統(tǒng)自動調(diào)零
自動控制測量室溫度變化
溫度可從30度調(diào)節(jié)到130度,精度為1度,電熱調(diào)節(jié)器適合測量電導(dǎo)液


◆測量原理:
連接不同測量的兩個電熱調(diào)節(jié)器懸掛在恒溫測量池中,測量池充滿了溶劑的飽和蒸汽。測量探頭*初表面都覆蓋溶劑液滴,因而它們之間沒有溫差。將一個探頭表面的溶劑液滴換成溶液液滴,由于溶液表面更低的溶劑蒸氣壓,會導(dǎo)致溶劑蒸氣冷凝。冷凝釋放的熱使溶液液滴的溫度升高,同時導(dǎo)致蒸氣壓升高。當測量池和溶液液滴表面的飽和蒸氣壓達到氣壓平衡時,溶液液滴達到一個相對穩(wěn)定的溫度。溫度通過測量系統(tǒng)直接轉(zhuǎn)變成電壓信號,從而得到測量值。測量值與溶液的滲透濃度成比例,但加熱不夠或溶液聚合物的不當操作都會影響測量結(jié)果。

由于聚合物溶液滲透壓與濃度的非線性行為,至少需要測量三個濃度梯度的溶液。通過線性回歸的統(tǒng)計方法計算測量結(jié)果。

◆OSMOMAT 070 蒸氣壓力滲透壓計應(yīng)用:
適合測定溶解在不同有機溶劑中聚合物平均分子量和水溶液的滲透壓。測量范圍為40-50000g/mol有機溶
液,水溶液為5000g/mol。
