Breaking Down the Features of Thermo Fisher Scientific ORION Sure-Flow Cyanide Ion Selective Electrode, Combination, Solid State, Thermo Fisher Scientific Scientific 9606BNWP
Specifications
The Thermo Fisher Scientific ORION Sure-Flow Cyanide Ion Selective Electrode, Combination, Solid State, Thermo Fisher Scientific Scientific 9606BNWP boasts several key specifications that contribute to its performance. Its ion concentration range spans from 260 ppm down to 0.2 ppm, or expressed in molarity, from 10⁻² to 8 x 10⁻⁶ M. This wide range makes it suitable for various applications, from high-concentration industrial wastewater to trace analysis in drinking water.
The temperature range is specified as 0 to 80°C, which covers most standard laboratory and many field conditions. Its body material is epoxy, offering a good balance of durability and chemical resistance, crucial for use in diverse sample types. The innovative Sure-Flow junction is a critical design element, designed to resist clogging and ensure consistent performance.
It features a standard 1 m lead length and a common BNC connector, ensuring compatibility with a vast array of modern meters, including those from Thermo Scientific and other manufacturers. This model is a combination electrode, meaning it integrates the sensing element and the reference element into a single unit, simplifying operation and reducing the number of connections. The Thermo Fisher Scientific Scientific number for this unit is 9606BNWP.
Performance & Functionality
The primary function of this ISE is accurate and reliable cyanide detection, and it excels in this regard. Its performance in measuring cyanide ion concentration is consistently within expected parameters for this type of electrode. The electrode’s response time is reasonably fast, and the readings are stable after a short equilibration period, which is vital for high-throughput labs.
A significant strength is its Sure-Flow junction; it genuinely minimizes clogging issues that plague other electrode designs. This drastically reduces the frequency of maintenance and the frustration associated with blocked junctions, especially when dealing with complex samples. The electrode’s ability to function effectively with small sample volumes (as low as 5 mL) is another major performance advantage, conserving valuable or limited sample material.
However, it’s important to note that for measurements below 0.2 ppm, the product literature recommends using a Silver/Sulfide electrode, indicating this particular model has limitations at the very lowest detection limits for cyanide. While excellent for its specified range, users needing to quantify sub-ppm levels with high precision might require alternative solutions. The need for the specific filling solution (34117-965) and ionic reagent (34185-155) is a minor functional requirement that users must be aware of.
