结构如下:
这里有个以前别人发的manual,第三章就是讲维护的

cary 50采用了非常多的先进技术,大家可以讨论下。特别想希望tutm能给解读下附件
。
特点如下:
1.最大扫描速度24000nm/分,这意味着 扫描190-1100nm整个波段仅需要3秒钟.
2.数据收集速度80 点/秒 ,在动力学测量中,能得到完整的数据
3.测定样品的收光度高达3Abs,所以经常不需要样品稀释
4.高强度脉冲氙灯仅读取数据时闪亮,所以不会引起光酸样品的降解
5.高强度脉冲氙灯使之可以使用光束分裂器,不会因为能量损失引起过度的光度噪音,优于样品和参比光束同时被修正,所以不会随扫描速度变化而发生位移
6.高度聚集的小光斑,使用非常适合用光纤探头,基于上述原因,使用微量池时亦能得到很好效果
7.Cary 50可以开着样品室盖工作,不受室内光线性的影响
基本上tutm介绍的所有先进技术都有了。
看看这7个特点有什么特殊含义呢
特点1,采用的应该是固态检测器,比如CCD,或者CMOS
特点2,12.5ms/点,不知道这算不算先进。
特点4,这就是以前chemweb问过的如何防止光解。
特点7. 这点不理解,它的详细解释如下
The Cary 50 is unaffected by room light. You can operate with the sample compartment open or closed, you won't notice the difference. So, if your sample won't quite fit in the sample compartment, it's OK, you can leave the lid off. If you want to keep dust, dirt and room light out of the sample compartment, then you can use the lid.
不知道大家能不能帮解释下。
还有一个特点是
he Cary 50 gets its power from the PC, it is only on when the PC is switched on. This also means that if something goes wrong with the electronics, fixing the problem is as simple as changing the board in the PC.
它的意思是只要换个板子就行,这有啥好说的呢?
看了下cary 50的附件,挺玄的,
附件分Solid Sample Accessories 和Liquid Sample Accessories,固定样品附件啥意思呢?怎么检测固体样品呢?
附件网址是这里,谁能详细说下吗?

下图是一些比色皿
1号比色皿特点:
These self-masking cells are stoppered to prevent solvent vaporization.hey can be used with the Cary Temperature Probe accessory which allows monitoring of the solution temperature inside the cell.
2号比色皿特点:
This cell comes with a magnetic stirrer bar and features a circular stirring well at its base to accommodate the stirring bar. This ensures that the bar spins easily. The cell is suitable for use with the Cary 1, 3, 4, 5, 100, 300, 400& 500series peltier thermostatted multicell holder which features both peltier temperature control and magnetic stirring.
3号比色皿特点:
This innovative design features a lens on the face of the cell to capture more of the incident light.
上面有透镜,很神奇。
4号比色皿特点:
These solid quartz cells offer low volume, short pathlength and excellent heat transfer. We recommend them for use when you have a limited sample volume and either the sample is highly concentrated or you are working in a region where the solvent absorbs strongly. These microcells are also ideal for temperature controlled experiments.
5号比色皿特点:
These cells require as little as 2.5 µL of sample.. They have the optimum 'Z' height (the distance between the base of the cell and the centre of the light beam) for the current range of Cary spectrophotometers. The sample can be inserted and retrieved from the cell with a pipette or syringe.
由于解释的不好,所以没翻译。
