UV Highlights Nitrate Sensing Applications of New UV-C LED Technology
SF1
series UV-C LEDs: A better way to detect nitrate contamination in water
Brisbane, Australia, 17th
November, 2022 - Newly-developed
ultraviolet LEDs from Silanna UV are ready to take Nitrate Sensing
applications into a new era, promising cleaner and safer drinking water
that is free from nitrate contamination. Silanna’s SF1 series of LEDs
leverage the company’s patented short period superlattice (SPSL) technology
that provides industry-leading performance and power output in the
challenging 230nm-260nm UV range (Far UV-C and Deep UV-C). Silanna now
provides a complete reference design for a nitrate detector based on
this technology.
As well as nitrate detection, Silanna’s SF1 and SN3 UV LEDs are ideal
for sterilization, water and gas sensing, instrumentation, and medical
analyzers.
The
increasing challenge of nitrate contamination in water
Nitrate contamination of drinking water is a growing threat around the
world, with nitrates from agricultural, industrial and natural
biological processes increasingly contaminating water supplies as
populations grow and expand. Detection of nitrates traditionally relied
on an expensive process in which broadband light generated by a UV lamp
is passed through spectroscopy to extract the far UV-C wavelength
needed for sensing.
Silanna’s
SF1 series LEDs provide a far more cost-effective, compact,
reliable, low-power alternative to traditional methods of nitrate
detection – and, thanks to patented technology, now lead the industry.
In particular, SF1 series UV-C emitters with a peak wavelength under
235nm and a Full-Width-Half-Max (FWHM) of 10nm are an ideal candidate
for nitrate sensing applications.
Nitrate
sensor reference design
To help users evaluate this new technology and develop products based
on it, Silanna has created a nitrate sensing reference design featuring
the company’s SF1 series LEDs. This module rapidly and accurately
measures the nitrate content of a liquid sample.
The microcontroller-based reference design features a capacitive touch
display, safety interlock, and compensates for thermal effects to
maintain accuracy and avoid warm-up delay. The UV-C LEDs package’s
built-in 30-degree parabolic lens eliminates the need of secondary
optics, making the system even more compact and cost effective. The
module requires less than a second to make a measurement, not only
saving time, but also extending component lifetime to over 100,000
measurements, and the concentration of the nitrate is measured at a
resolution of 0.01mg/L-N according to estimates.
