安东帕旋光仪的九则问题解答分享

 安东帕旋光仪是(shi)测(ce)定(ding)旋(xuan)(xuan)(xuan)(xuan)(xuan)光(guang)性物(wu)质旋(xuan)(xuan)(xuan)(xuan)(xuan)光(guang)度(du)的(de)仪器。通(tong)(tong)(tong)过(guo)对样品旋(xuan)(xuan)(xuan)(xuan)(xuan)光(guang)度(du)的(de)测(ce)量，可以分析确定(ding)物(wu)质的(de)浓度(du)、含量及纯度(du)等(deng)。自然光(guang)通(tong)(tong)(tong)过(guo)起偏(pian)(pian)镜后产(chan)生平(ping)面偏(pian)(pian)振(zhen)光(guang)，如果旋(xuan)(xuan)(xuan)(xuan)(xuan)光(guang)管(guan)中盛装(zhuang)的(de)为(wei)旋(xuan)(xuan)(xuan)(xuan)(xuan)光(guang)性物(wu)质，当偏(pian)(pian)振(zhen)光(guang)通(tong)(tong)(tong)过(guo)该物(wu)质溶液时，偏(pian)(pian)振(zhen)光(guang)的(de)角(jiao)度(du)会向左或向右旋(xuan)(xuan)(xuan)(xuan)(xuan)转(zhuan)一定(ding)角(jiao)度(du)，这(zhei)时，为(wei)了让(rang)旋(xuan)(xuan)(xuan)(xuan)(xuan)转(zhuan)一定(ding)角(jiao)度(du)后的(de)偏(pian)(pian)振(zhen)光(guang)能通(tong)(tong)(tong)过(guo)检(jian)偏(pian)(pian)镜光(guang)栅，需要将检(jian)偏(pian)(pian)镜旋(xuan)(xuan)(xuan)(xuan)(xuan)转(zhuan)一定(ding)角(jiao)度(du)，在目镜处才(cai)能看到明亮。这(zhei)个所旋(xuan)(xuan)(xuan)(xuan)(xuan)转(zhuan)的(de)角(jiao)度(du)就是(shi)该待(dai)测(ce)物(wu)质溶液的(de)旋(xuan)(xuan)(xuan)(xuan)(xuan)光(guang)度(du)
