1. Introduction

Thank you for buying a Specac product. We trust it will provide you with

invaluable and excellent service in use.

The Quest Single Reflection ATR Accessory is designed for the

quantitative and qualitative analysis of solids, powders, liquids, pastes

and gum-like samples using mid-IR spectroscopy at a nominal 45°

incident angle under ambient or elevated temperature conditions.

The Quest is based upon Synopti-Focal technology –an innovative

synoptic focusing array of highly reflective gold coated mirror only optics

–in an optical unit fitted with interchangeable ATR puck assemblies

(choice of diamond, ZnSe, Ge or Si). The ATR crystal is mounted in

either a Standard (flat), Liquid or Heated Puck Assembly. For solid

samples, where good contact with the ATR crystal is required, a clamp

arm produces a highly reproducible load of 40 lbs.

The use of mirror optics maximizes the spectral range as follows:

ATR Crystal

Range (cm-1)

Diamond

AR Coated

7800 - 400

Non-AR Extended Range

10000 - 10

ZnSe

Specular Reflectance measurements are also possible by the use of a

specular reflectance puck at a nominal 45 ° angle.

2. Safety

Caution! Always use personal protective equipment (PPE)

when operating this device and follow local safety operating

procedures and practices with respect to potential toxic and

flammable sample substances.

Make sure that all samples intended to be used with the ATR are

chemically compatible with the accessory surfaces, including:

•The ATR crystal material (diamond, ZnSe, Ge, or Si)

•The indium sealing material around the crystal.

•Stainless-steel used in the puck and anvil components.

•Anodized aluminum & Viton O-ring in the volatiles cover.

•For Arrow only: polypropylene slide, thermoelastic seal (SBS-

SEBS), anodized aluminum puck.

Safety data sheets (SDS) are available in the product support section of

the Specac web site where required and are provided with each crystal

type. As an alternative please contact your Specac representative for

further details.

It is recommended to wear suitable gloves and eye protection PPE at all

times when using this device.

Important! This manual should be read in conjunction with

the Arrow QS user manual where applicable.

Important! This manual should be read in conjunction with

the manual for the heated puck and USB temperature

controller where applicable.

5. Installation

5.1. Mounting the Quest into the Spectrometer sample

compartment

Figure 5-1: Quest ATR Accessory –Optical Unit and ATR Puck Assembly

The Quest ATR Accessory is supported on a Benchmark™ baseplate

when installed into a spectrometer. A Benchmark™ baseplate has three

pillars across the front for location/fixing and a fourth to the rear for

support only. The thumb screw (1) at the front of the Quest ATR optical

unit screws into the front central pillar, while the outer studded pair locate

in slots beneath the Quest unit.”

Note: Install the Benchmark™ baseplate in the spectrometer first

before locating the Quest ATR Accessory.

Fixing holes and studs in the Benchmark™ baseplate will vary

depending upon the make and model of the spectrometer. Refer to the

Benchmark™ baseplate Installation Guide/User Manual.
