Gateway™ ATR Flow Through Top Plate 1. Introduction Thank you for purchasing a Specac Product. This user instruction manual for the Gateway™ ATR Flow Through Top Plate P/N GS11116 is to be used in conjunction with the user instruction manual provided for the Gateway™ 6 Reflection ATR Accessory against P/N GS11165 (2I-11165-4). - Page 6 User Manual rubber – as supplied) combined with a peristaltic liquid pumping system, or held static over the crystal when the pump is turned off. The Gateway™ ATR Flow Through Top Plate has been designed with the capability to remove the ATR crystal for thorough cleaning or using a replacement ATR crystal material in the Top Plate if desired.

Gateway™ ATR Flow Through Top Plate 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 possible you should follow a procedure for safe handling and containment of the type of sample to be used. -

User Manual 3. Unpacking and Checklist The Gateway™ ATR Flow Through Top Plate is supplied packed in a black plastic carry case. The carry case contains the following: • Flow Through ATR Top Plate with Zinc Selenide crystal (or as specified from germanium and silicon options) •... - Page 9 Gateway™ ATR Flow Through Top Plate 4. Alignment of the Gateway™ ATR Flow Through Top Plate The Gateway™ ATR Flow Through Top Plate is to be installed onto the optical unit (GS11170) of the Gateway™ ATR Accessory for operation in the study of flowing or static liquids at room temperature conditions.
- Page 10 User Manual Fitting the Gateway™ ATR Flow Through Top Plate The Gateway™ ATR Flow Through Top Plate fits onto the top of the Gateway optical unit via alignment of the round hole (1) and slot hole (2) on the underside of the Top Plate over the two fixing location pins (3) on the optical unit.

User Manual 5. Introducing the Liquid Sample When the Gateway™ ATR Flow Through Top Plate has been correctly installed onto the optical unit and aligned, then operation for collection of a background spectrum and then a sample spectrum can begin. (Please see Spectral Collection Using the Gateway™... - Page 13 Gateway™ ATR Flow Through Top Plate plate (6). (See Fig 4). It does not matter which of the flow ports (5) is the inlet or outlet connection for flow. The clear silicone tubing supplied has dimensions of 1/4" O.D. and 1/8” I.D. and is pushed over the barbed hose type connectors on the flow ports (5).
- Page 14 User Manual 6. ATR Crystal Removal and Replacement The design of the Gateway™ ATR Flow Through Top Plate allows for the ATR crystal (7) to be removable for easier cleaning or if damage occurs and the crystal needs to be replaced. Crystal Removal from the Flow Through Top Plate If it is necessary to remove the crystal (7) for thorough cleaning of the Top Plate assembly of parts or to replace any damaged parts etc, the...
- Page 15 Gateway™ ATR Flow Through Top Plate 2) Between the underside of the clamp plate (10) and the ATR crystal (7) there is a protective lead pad (11). Carefully remove the clamp plate (10) away to gain access to the lead pad (11). (See Fig 7.) The lead pad (11) may be stuck close to the underside of the crystal (7) and so it needs to be removed very carefully away from the crystal.
- Page 16 User Manual When the crystal (7) and the lead pad (11) have been removed, it may now be easier to separate the lead pad (11) from the crystal. If the crystals (7) top sampling surface looks OK and can be cleaned carefully, then it may not be necessary to remove the lead pad (11) away for further cleaning prior to re-assembly and use.
- Page 17 Gateway™ ATR Flow Through Top Plate The Isolast gasket seal (8) is supplied already pre-cut to fit and is purchased against P/N GS11150. Should the Isolast gasket (8) be worn or damaged after inspection then replace with a new example. If changing for a new gasket (8), ensure that all parts of the old gasket are removed from the surface of the stainless steel top section plate (6) to provide a good surface for resealing.
- Page 18 User Manual 4) Carefully replace the lower clamp plate (10) over the lead pad (11) and crystal (7) and refit the four screws (9). Ensure that the lead pad (11) and crystal (7) are not dislodged from their central positioning. (See as for Fig 6.) 5) Exert a pressure at the middle of the lower clamp plate (10) with your thumb and tighten the four screws (9) a little at a time, in a rotational sequence, to apply the pressure to the lead pad (11),...
- Page 19 Gateway™ ATR Flow Through Top Plate Cleaning the Gateway™ ATR Flow Through Top Plate Intact The procedure for cleaning of the crystal (7) with its removal from the Top Plate assembly needs possibly to be carried out only very occasionally. To avoid the need for cleaning the crystal outside of the Top Plate assembly it is important to flush out any sample remaining within the sampling area cavity by cleaning through with a suitable solvent before storage.
- Page 20 User Manual useful to remove any Top Plate assembly from the optical unit and carry it to a safe area for solvent cleaning and wiping with a tissue and therefore minimise any risk of contamination being carried over to other components of the Accessory whilst in situ. Solvents such as water, methanol and acetone are suitable to use for cleaning purposes.
- Page 21 Gateway™ ATR Flow Through Top Plate Data Sheet For Zinc Selenide General Toxic and hard, yellow coloured crystalline powder when fused together as a solid can be used as a transmission window material or as a crystal material for attenuated total reflectance (ATR) FTIR spectroscopy. Insoluble in water, but attacked by strong acids and bases.
- Page 22 User Manual Keep powder or windows stored in a cool, dry container, with appropriate safety labelling. Data Sheet For Germanium General Hard and very brittle material, but can be shaped, cut and polished to form spectral transmission window or crystal for ATR spectroscopy. Because of its high Refractive Index value suffers from large reflection losses but these can be improved with antireflection optical coatings Is temperature sensitive and loses transmission when heated.
- Page 23 Gateway™ ATR Flow Through Top Plate Keep windows or crystal stored in a cool, dry container. Data Sheet For Silicon General Synonyms: Defoamer S-10. When powder is fused together, is used as a transmission window material. Very hard, but brittle and relatively inert material. Insoluble in water, resists acids and bases but is attacked by combination of hydrofluoric and nitric acid.
