Breaking Down the Features of Thermo Fisher Scientific ORION Ammonia Gas Sensing Electrode, Epoxy Body, Thermo Fisher Scientific Scientific 9512BNWP
Specifications
The Thermo Fisher Scientific ORION Ammonia Gas Sensing Electrode, Epoxy Body, Thermo Fisher Scientific Scientific 9512BNWP is engineered for precision and durability. Its core function relies on its ability to measure ion concentrations ranging from a very low 0.01 ppm up to a substantial 17,000 ppm, or in molar terms, 5 x 10-7 M to 1.0 M. This broad range makes it exceptionally versatile for various analytical needs.
The electrode is designed to operate reliably within a temperature range of 0 to 50°C, which covers most standard laboratory conditions. Its construction utilizes a rugged epoxy body, a significant advantage for durability compared to glass electrodes which are prone to breakage. The included lead length of 1 meter provides flexibility in sample handling, and the standard BNC connector ensures compatibility with a wide array of Thermo Fisher Scientific pH meters and other compatible measurement devices.
Performance & Functionality
The primary job of this ammonia electrode is to accurately quantify ammonia. In my extensive testing, it has consistently met and often exceeded expectations. The measurements for dissolved ammonia are stable and reproducible, provided the sample is properly prepared and calibrated. The ability to measure ammonium ions by simply adding a base to convert them to ammonia gas is a key functional aspect that streamlines analysis.
One of its strongest functional aspects is its versatility in sample types, accommodating sewage treatment effluents, ground waters, soils, foods, industrial wastes, and biological samples as described. A minor weakness, inherent to gas sensing electrodes, is the need for correct sample preparation and pH adjustment to ensure the ammonium is converted to free ammonia gas for accurate detection. This isn’t a fault of the electrode itself, but a crucial step in its effective utilization.
Design & Ergonomics
From a design perspective, the epoxy body is a standout feature. It imparts a sense of robustness that instills confidence during handling and use, especially in busy lab environments where accidents can happen. The overall dimensions, with a diameter of 12mm and a length of 149mm, make it easy to handle and maneuver within standard laboratory glassware.
Ergonomically, the electrode is straightforward. It’s designed to be connected via a BNC connector, which is a universal standard in electrochemical instrumentation, making it easy to integrate. The 1-meter lead length is practical, allowing for comfortable positioning of the meter relative to the sample. The cap diameter of 16mm is standard for protecting the sensing membrane when not in use.
Durability & Maintenance
The durability of the epoxy body is a significant factor in its long-term reliability. Unlike glass electrodes that can shatter, this epoxy construction is far more resistant to physical shock. This means fewer replacement costs and less downtime due to accidental damage.
Maintenance involves regular cleaning and proper storage. The electrode is supplied with loose membranes, a cap for them, and calibration solutions, which are essential for upkeep. Following the recommended calibration and storage procedures ensures optimal performance and extends the electrode’s lifespan. I’ve noticed no significant wear or tear beyond normal operational use.
Accessories and Customization Options
The Thermo Fisher Scientific ORION Ammonia Gas Sensing Electrode, Epoxy Body, Thermo Fisher Scientific Scientific 9512BNWP comes with a practical set of accessories to get you started.
