General:
Sensor spots are tiny planar pH mini sensors immobilized onto either polyester or glass supports. The latter is autoclavable. The sensor spots are glued inside chambers, flasks or disposables with translucent and non-fluorescent walls (e.g. glass, polyester, acrylic etc.). Then pH measurements can be done in a non-invasive and non-destructive way from outside and through the wall of your vessel.
With silicone glue (OX11100) you can glue the sensor spots inside your own chambers, flasks, disposables, or we can do it for you.
To use the sensor spots a fiber optic instrument and an external fiber cable (light guide) is required. The tip of the fiber cable delivers (blue) light to the backside of the sensor spot though the wall (and transparent glue). The front side of the sensor spot is in contact with the media (liquid or gas), e.g. the light is not passing through the media.
There are two ways of fixing the (external) fiber cable over the centre of the (internal) sensor spot:
1) A bare tip fiber cable (OX11150) is fixed with a special chamber (holder), or run through a Radiometer/Cameron dummy electrode adapter (CH10470) for fiber optic pHsensing in Radiometer/Cameron electrode chambers, cuvettes etc.
2) A fiber cable with a threaded SMA connector at the tip (OX11160) is screwed onto a fitting sitting on a velcro band adapter for curved chamber walls (OX11170) or planar walls (OX11180).
