Nano-Band™ Explorer Electrodes

Our patented Nano-Band™ electrode is optimally designed to allow extremely rapid & sensitive measurements of trace metals. The Nano-Band™ electrode consists of 100 sub-electrodes each with a surface area that is less than 2 square microns. Using advanced fabrication technology to produce our micro-electrode array, our electrodes exhibit superior mass transport and extremely small surface area. This combination ensures quick & sensitive measurements of trace metals. Measure ppm levels instantly, ppb levels in seconds, and ppt levels in minutes.

Carbon Nano-Band™ Electrode

The carbon Nano-Band™ electrode is ideally suited for directly measuring arsenic(III). Simple step-by-step oxidation and reduction protocols allow the measurement of Total Arsenic concentration in your samples. Measure arsenic to < 1ppb.

Chemical
Resistance		 Acidic solutions to pH = 1, avoid hydrofluoric acid and aqua regia (dilute 50:1 aqua regia is acceptable)
Basic solutions to pH = 10
Solvents: Alcohols, alkanes, and xylenes are acceptable; avoid ketones (particularly acetone) and methylene chloride
Other: Food oils and most fuels are acceptable
Electrochemical
Range		 Typically –0.7 V to +0.8 V (with thin-film gold) vs. Ag/AgCl reference electrode in pH = 4.0 phthalate and pH = 4.6 acetate buffers. Range is reduced to -0.4 V to +0.65 V when using 2M hydrochloric acid.
General Cleaning Clean with distilled or deionized water. Mild solutions of nitric acid or isopropyl alcohol may also be used. Low power ultrasonic cleaning is also acceptable.
Storage Nano-Band™ electrodes can be stored wet or dry. For dry storage, rinse first with distilled/deionized water and blow dry. For wet storage, store in distilled/deionized water or in weak nitric acid solutions (pH > 4). Dry storage is recommended for periods longer than three days.
