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). Understanding of the
Gateway™ ATR Accessory itself helps in usage of any alternative ATR
Top Plates that are compatible with this ATR system.
The Gateway™ ATR Flow Through Top Plate P/N GS11116 is an
alternative Top Plate that can be used on the optical unit (P/N
GS11170) of the Gateway™ ATR Accessory. The Gateway™ ATR
Accessory supplied as standard for a kit of parts under P/N GS11165,
provides for an optical unit (GS11170), a trough top plate assembly
fitted with a 45° ZnSe crystal (GS11166), a flat top plate assembly
fitted with a 45° ZnSe crystal (GS11133) and a clamp assembly
(GS11171). (See user instruction manual 2I-11165-4).
Note:
Any
Gateway™ ATR Top Plate assembly can also be used on
older Ben
chmark™ ATR optical units, P/N’s GS11160, GS11110
and GS11180.
Using the
Gateway™ ATR Flow Through Top Plate in conjunction with
any of the above optical unit systems, a liquid sample can be flowed or
held static over a 6 Reflection event ATR crystal to be studied at
ambient temperatures. Chemical interactions for the mixing of sample
species in a flowing environment may also be monitored. (e.g. a solid
sample can be deposited onto the ATR crystal and a fluid can be
flowed over the sample to observe any changes spectroscopically.)
A liquid sample is introduced to the ATR crystal analysis area via
connection of tubing to the inlet and outlet sample flow ports on the top
section of the Gateway™ ATR Flow Through Top Plate. The liquid
sample flows through a cavity with a volume of 550 microlitres, when
covering over the entire top surface area of the crystal. The liquid
sample can be kept flowing using a suitable flow tubing (clear silicone
