Analyzing Spectroscopic Samples in the Laboratory with a Single-Reflection ATR Accessory

The Quest is a single-reflection ATR system designed for the IR analysis of chemicals and other samples in the lab. The Quest uses a monolithic diamond ATR crystal to produce optimum results, and its innovative optical design means it can be easily integrated into existing infrared systems. The Quest is industry leading in both ability and value.

The Quest’s monolithic diamond is extremely tough and chemically inert. This means the Quest can be used to compress hard, brittle solids at high forces without being damaged, and can also be used to test chemically reactive samples, meaning the instrument is incredibly versatile. The relatively large (1.8 mm) sample area of the ART surface also means adequate contact can be achieved, even when the sample is very small.

Quest的光学元件使用Specac的新型Synopti-cocal阵列技术，该技术将涂有金色的光学元件与精确形状的优体镜一起使用，以提供ATR晶体和样品的最佳入射角。这个新型的光学系统通过大波长范围提供了非凡的IR传输，以提供富含IR光谱的数据。

The Quest’s pucks can be easily swapped depending on analysis needs. Four different versions are available:

• The ‘standard’ diamond puck for analysis in the mid-IR (7,800 – 400 cm^-1）
• A diamond puck with an extended wavelength range for analysis in the mid to far-IR (10,000 – 40 cm^-1）
• GE晶体冰球，用于分析强烈吸收IR的样品
• ZNSE冰球，用于分析较软的样品

每个ATR冰球都将其固定在适当的固定不锈钢冰冰球上，该冰球粘合到强大的金属密封件上，可确保与大量样品的兼容性。提供了具有平面和颗粒形状的冰球，以寻求与不同形状样品的兼容。当不使用砧座时，可以将其保存在任务的顶板上。

通过使用压力塔来确保测量可重复性，当达到选定的压力极限时，该压力塔会大声咔嗒声。手臂也可以旋转到侧面以提供冰球的通道，无论是用于清洁还是交换。

The Benefits of a Monolithic Diamond

使用钻石冰球的ATR配件倾向于有两个版本之一。有冰球，例如使用单片钻石晶体，还有其他冰球，其中还有使用光学元素，例如Znse，涂有薄钻石晶片。

后者不是可取的，因为它们在直接载荷下往往很脆弱。支撑材料限制了它们可以工作的波长范围，它们可以被拆卸（这会引入错误的结果），并且显示出钻石吸收功能的减少（在2,000至2,500 cm之间^-1），因为钻石层是如此薄。

On the other hand, monolithic diamond pucks are far more durable and harder, meaning they can be used to compress even hard solids with little risk of damage. They also provide better results and have an extremely wide wavelength range for transmission, which spans from 10,000 to 40 cm^-1。

The Benchmark Baseplate^TM

The Benchmark Baseplate system allows the Quest to be moved from one instrument to another in the laboratory with minimal effort. The Baseplate is an interface between the Quest and the instrument, which is securely attached to the Quest via only a single screw. The Baseplate makes it easier to switch between instruments and is specific to instrument models. When ordering a Quest, users should specify the spectrometer (or similar) that they are using.
