The ISO-NOP is a popular, robust and high performance sensor encased within a 2 mm diameter disposable stainless steel protective sleeve. The tip of the sleeve is covered with a NO-selective membrane. Replacement membrane sleeves can be purchased separately and require an internal electrolyte.
- Excellent sensitivity to NO: 2 pA/nM
- Rapid response time: <5 s
- Highly sensitive
- Lowest detection limit: 1 nM
- Upper detection limit/range: 80 µM (beyond 80 µM, sensor accuracy is not guaranteed)
- 2 mm NO sensors for NO detection in cell cultures
A simple change in experimental protocol enables the ISO-NOP to be conveniently used for indirect rapid accurate determination of nitrite (NO₂) and nitrate (NO₃) concentration in samples. Using this method a detection limit for NO₂ or NO₃ as low as 1 nM is routinely possible.
Ideal for cell cultures, cell suspensions and many other applications.
