Quest Single Reflection ATR Accessory

1. ntroduction

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 ambient

temperature and pressure conditions. rincipally, ATR spectral

measurements at a nominal 45° incident angle are made, but specular

reflectance measurements at the same nominal incident angle can be

made using an optional specular reflectance puck assembly. Sufficient

sample is required to cover an ATR crystal surface offered from a

single crystal diamond, zinc selenide (ZnSe), germanium (Ge) and

silicon (Si) flat crystal top plate assembly (puck) options.

The Quest ATR Accessory is based upon Synopti-Focal technology –

an innovative synoptic focusing array of highly reflective gold coated

mirror only optics – in an optical unit that supports the interchangeable

ATR crystal puck assemblies. An IR light beam that is projected

towards the ATR crystal is presented at a nominal 45° angle of

incidence to the sample surface. As the optical unit of the Quest ATR

Accessory consists of mirrors as reflective components only, it allows

for as wide a range as possible of the spectral frequency throughput

for the specific ATR crystal puck assembly being used. For mid IR

spectral data the typical spectral range that can be collected for the

different ATR crystal puck types are as follows:

Diamond puck – 7,800cm-1 to 400cm-1 (AR coated crystal).

Diamond puck – 10,000cm-1 to 40cm-1 (Extended Range – non-AR

coated crystal).

ZnSe puck – 7,800cm-1 to 500cm-1. (AR coated crystal).

Germanium puck – 5,500cm-1 to 480cm-1. (AR coated crystal).

Silicon puck – 8,333 to 100cm-1. (Non-AR coated crystal).

As mentioned, there is also an option in use of the Quest ATR

Accessory for the spectral measurement of solid sample types such as

flat surface films by the specular reflectance technique. The ATR

User Manual

crystal puck assembly is replaced with a puck assembly that has no

ATR crystal fitted to allow for the nominal 45° incident angle of light to

be projected directly to the solid sample surface.

An adjustable clamp arm assembly with a set load torque limiter screw

knob is permanently affixed to the optical unit. There is a choice of self-

levelling flat or concave pellet compression head anvils to use with the

clamp arm assembly depending upon the sample type to be studied

using an ATR crystal puck assembly. (No anvil is used for specular

reflectance measurements of solid sample types.) The torque limiter

screw knob provides for a consistent and reproducible load to either

one of the flat or pellet anvils to enable excellent close contact of a

solid sample with the ATR crystal. In operation, the entire torque screw

knob is rotated until a sufficient load and hence pressure has been

applied to the sample. The torque screw knob will continue to rotate

when the set load is reached, but the drive connection slips and no

more force will be applied. A “clicking” sound with continual rotation of

the knob acts as the indicator when the set applied load has been

reached. When using the clamp arm assembly with a compression

head anvil for pressure application to solid sample types, the anvil

does not rotate against the sample. This ensures that heat is not

generated by friction which may cause changes to the sample, and the

sample is not displaced from the correct sampling position.

The optical unit of the Quest ATR Accessory can be supplied in a

variety of different top surface colours on a light grey optical unit. The

standard colour is black (B), but there are options of red (R), yellow

(Y), orange (O), green (G), aqua (A) and purple ( ).

2. Safety Considerations

With use of any spectroscopic accessory that involves the study of a

wide range of chemical samples, the associated risk in handling may

mostly be attributed to the specific sample type to be handled itself. As

far as it is possible you should follow a procedure for safe handling and

containment of the type of sample to be used.

With respect to safety of use specifically to the Quest ATR Accessory,

this uses different crystal materials for the ATR crystal puck

assemblies where a sample is bought into contact for analytical

spectroscopic study. As standard, Diamond (type IIIA), Germanium

(Ge), Zinc Selenide (ZnSe) and Silicon (Si) are the four crystal

materials of choice that can be used.

Caution: Out of these four different crystal types, ZnSe is

the most potentially hazardous material with respect to

toxicity risk in use and handling.

Diamond, Ge and Si crystal materials can be considered relatively safe

to use, although Ge and Si may be harmful to the body if ingested in

significant quantity. The general rule when working with any crystal

material (and sample) is to always wear gloves and safety gear (e.g.

safety spectacles) when handling to obviate the risk of contact with the

skin.

rovided with each crystal version of puck assembly is a window

material safety data sheet for the crystal material itself that can be

consulted for safe handling. A copy of each of these datasheets can

also be found in this Quest instruction manual in the Notes On

Cleaning Section found on pages, 40, 41, 42 and 43.

4. nstallation Using Benchmark™ Baseplate

Fig .

Quest ATR Accessory – Optical Unit with Clamp Arm/Anvil

Assembly and ATR Crystal Puck Assembly

The Quest ATR Accessory is supported on a Benchmark™ baseplate

when installed into a spectrometer. The Benchmark™ baseplate

typically has three support pillars (one flat support pillar towards the

rear and two at the front with location pins) and a fourth front central

pillar into which the fixing thumb screw ( ) of the Quest ATR optical

unit is tightened.

Note: It is normally best to install the Benchmark baseplate in

the spectrometer first before locating the Quest ATR

Accessory.

Fixing holes and studs in the Benchmark™ baseplate will vary

dependent upon the make and model of the spectrometer into which

the Quest ATR Accessory is to be installed. For details on how to

install your accessory in the spectrometer, refer to the Benchmark™

baseplate Installation Guide/User Manual supplied.

User Manual

5. Alignment Procedure for Quest ATR

When you have installed the Quest ATR Accessory into your

spectrometer on its appropriate Benchmark™ baseplate, you should

check for alignment of the accessory. An overall spectral throughput of

light energy between 10% and 35%, dependent upon the ATR crystal

puck assemblies and spectrometer used should be achievable. The

Quest ATR Accessory with your choice of crystal puck will be supplied

having a preliminary factory alignment. On installation, some

transmitted energy should be recorded on the spectrometers

energy/light detector monitoring system, but it will be necessary to

maximize the optical throughput for any specific spectrometer by

adjusting the mirrors in the optical unit of the Quest ATR Accessory. To

carry out any alignment procedure one of the Quest ATR flat crystal

puck assemblies must be fitted to the optical unit.

Fitting of the Quest ATR Crystal Puck to the Optical Unit

Seven different versions of Quest ATR crystal puck assemblies can be

fitted to the optical unit. They are:

Quest ATR Diamond crystal puck, /N GS10810.

Quest ATR Diamond extended range crystal puck, /N GS10811.

Quest ATR ZnSe crystal puck, /N GS10812.

Quest ATR Ge crystal puck, /N GS10813.

Quest ATR Si crystal puck, /N GS10819.

Quest ATR Diamond crystal puck with diamond like carbon (DLC)

coating, /N GS10826.

Quest ATR Diamond extended range crystal puck with diamond like

coating (DLC), /N GS10827.

The ATR crystals of these puck assemblies have an antireflection (AR)

coating on their underside surfaces for improved light throughput

characteristics, except the extended range diamond crystal pucks

/N’s GS10811 and GS10827, and the silicon puck /N GS10819.

Serial number and puck crystal identification labels are affixed to the

underside surface of the puck assembly. (A note of the serial number

of your crystal puck assembly can be made on page 47 of this user

instruction manual for your reference records.)
