    Gateway™ ATR Electrically Heated Trough Top Plate 1. Introduction Thank you for purchasing a Specac Product. This user instruction manual for the Gateway™ ATR Electrically Heated Trough Top Plate P/N GS11155 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 Usually, a liquid sample to be analysed is just simply placed to cover over the ATR crystal analysis area of the Trough Top Plate assembly. However, thin polymer films or semi-solid type samples can also be analysed spectroscopically if the film is cut to the approximate size of the crystal surface area and the Gateway™...
  • Page 7: Safety Considerations

    Gateway™ ATR Electrically Heated Trough 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.
  • Page 8 User Manual Caution: No user serviceable parts within the temperature controller supplied, contact the manufacturer or approved service agent for advice if the product is not functioning correctly or is visibly damaged. Caution: If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired Warning: Risk of burns when operated at high...

    User Manual 4. Alignment of the Gateway™ ATR Electrically Heated Trough Top Plate The Gateway™ ATR Electrically Heated Trough Top Plate is to be installed onto the optical unit (GS11170) of the Gateway™ ATR Accessory for operation in the study of static liquids or semi-solid samples and thin films over the temperature conditions from ambient to 200°C.
  • Page 11: Fitting The Gateway

    Gateway™ ATR Electrically Heated Trough Top Plate Fitting the Gateway™ ATR Electrically Heated Trough Top Plate The Gateway™ ATR Electrically Heated Trough 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.
  • Page 12 User Manual Important: Care must also be taken to see that from installation there is no unnecessary stress or strain applied to the integrally fitted power/thermocouple cable, which could cause damage to the thermocouple. Avoid sharp bends of this cable at the end attached to the Heated Trough Plate. Fig 3.
  • Page 13: Analysing Different

    Gateway™ ATR Electrically Heated Trough Top Plate 5. Analysing Different Sample Types When the Gateway™ ATR Electrically Heated Trough Top Plate has been correctly installed onto the optical unit and aligned, then its integral power and thermocouple cable assembly with the six-way bayonet plug of the Top Plate assembly is to be connected to its appropriate socket at the rear of the 4000 Series Temperature Controller.
  • Page 14: Paste Samples

    User Manual As much of a liquid sample should be removed from the crystal (6) area with a pasteur pipette when the Heated Trough Top Plate assembly is cool to touch if any elevated temperature measurements have been taken. It is recommended that the Heated Trough Top Plate is also removed away from the optical unit to a safe area for cleaning before introducing the next sample or after use.
  • Page 15: Semi -Solid Samples

    Gateway™ ATR Electrically Heated Trough Top Plate carefully using soft lens cleaning tissues to wipe the sample clear of the crystal (6) while cooling. Remove the last traces of the sample when the Top Plate assembly has cooled sufficiently to handle by using fresh tissues soaked in a suitable solvent.
  • Page 16 User Manual To analyse a semi-solid sample such as a thin film, the film sample must be prepared by cutting to size to cover over the entire surface of the ATR crystal (6) in the recess of the trough area. The PTFE pressure bar (7) is then very carefully placed over the film surface on top of the crystal (6).

    Gateway™ ATR Electrically Heated Trough Top Plate 6. ATR Crystal Removal and Replacement The design of the Gateway™ ATR Electrically Heated Trough Top Plate allows for the ATR crystal (6) to be removable for easier cleaning or if damage occurs and the crystal needs to be replaced. Crystal Removal from the Heated Trough 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 18 User Manual Note: Do not touch the two slot head tensioning screws (9) as these hold the components of the lower clamp plate assembly (10) together for containment of the internal springs. 2) Between the underside of the lower clamp plate assembly (10) and the ATR crystal (6) there is a protective lead pad (12).
  • Page 19 Gateway™ ATR Electrically Heated Trough Top Plate (6) itself has been removed from its centralised position in its recess of the main body plate (4). Therefore, support the crystal (6) and the lead pad (12), with one hand and turn over the Top Plate assembly so that the crystal (6) can fall out to drop into the palm of your hand.
  • Page 20 (8) replacement exposes electrical components which should not be touched other than by qualified electrical personnel. If a new Kalrez gasket (8) is ever required, please contact Specac at techsupport@specac.co.uk to arrange for return of the item to Specac to carry out the service.
  • Page 21: Replacing Thec

    Gateway™ ATR Electrically Heated Trough Top Plate Replacing the Crystal in the Top Plate Assembly 1) Having cleaned all of the parts sufficiently and whether installing a new or cleaned crystal (6), re-assemble the Gateway™ Electrically Heated Trough Top Plate first by carefully inserting the ATR crystal (6) into the recess channel of the main body plate (4) with the longer top surface of the crystal pressing against the Kalrez gasket (8) and the angled faces of the crystal (6) pointing upwards.
  • Page 22: Cleaning The Gateway

    User Manual 3) Carefully replace the lower clamp pressure plate (10) assembly over the lead pad (12) and crystal (6) and refit the two screws (11). Ensure that the lead pad (12) and crystal (6) are not dislodged from their central positioning. (See as for Fig 6 and Fig 5.) 4) Stand the re-assembled Electrically Heated Trough Top Plate on a tissue covering a work surface and test for leaks.
