Why using Zlements laboratory testing?
At Reef Zlements, we're not just offering ICP testing — we're investing in the future of reef keeping.
We’ve made significant investments in both advanced analytical equipment and specialist talent, ensuring our testing services meet the highest standards of scientific accuracy. Our in-house laboratory is equipped with state of the art instrumentation, typically reserved for pharmaceutical and industrial analysis — now dedicated to the reefing hobby.
Before results are issued, each sample is processed and analysed, with all results reviewed and interpreted by trained analytical chemists who understand both the science and the unique demands of marine aquariums. This enables us to deliver not only numbers but also clear, actionable insights that support coral health and system stability.
By bringing advanced chemistry into the hands of reef keepers, we aim to raise the standard of care across the hobby — with faster turnaround times, UK/EU-based support, and a dosing philosophy rooted in accuracy.
When you test with Reef Zlements, you're not just checking your water — you're partnering with a team that’s deeply invested in reefing success through science.
At Zlements, precision isn't just a goal — it's our foundation. Our cutting-edge laboratory operates within a dedicated, positive-pressure cleanroom, meticulously designed to minimise and remove floor and airborne contamination, upholding the highest standards of analytical integrity and sample purity.
We harness the power of advanced analytical techniques to deliver insights you can trust. ICP-OES (Optical Emission Spectrometry), ICP-MS (Mass Spectrometry) for ultra-trace detection, Ion Chromatography for nutrient and anion analysis, Robotic Titration for pH and alkalinity measurements, colourimetry and conductometry for nutrient and conductivity (salinity conversion) measurements.
To further safeguard accuracy, we produce our own ultra-pure water in-house, ensuring reagent-grade consistency across every stage of testing.
Every measurement is carefully validated by our team of expert analysts. Every result is the product of rigorous methodology and a relentless pursuit of excellence.
At Zlements, science meets passion, empowering us to push the boundaries of reef chemistry analysis and product innovation — helping you build healthier, more vibrant reefs.
We offer a range of advanced water testing services to take the guesswork out of reefkeeping with Reef Zlements ICP Testing – a service designed for reef aquariums of all sizes.
Below are detailed descriptions of our Standard ICP, Advanced ICP, and ICP-MS testing services:
Standard ICP Testing
Our Standard ICP (Inductively Coupled Plasma Optical Emission Spectrometry) Testing utilises our in-house SPECTROGREEN DSOI ICP-OES instrument. This state-of-the-art equipment features a unique radial dual side-on interface, capturing emitted light from both sides of a vertical plasma with only a single extra reflection. This design provides twice the sensitivity of conventional radial-view models and matches the sensitivity of newer vertical-torch dual-view systems. Recommended by ICP specialists at Spectro for saltwater analysis, our technology ensures consistent and precise measurements, free from matrix interferences.
This detailed analysis provides reef keepers with precise insights into their aquarium's water chemistry, enabling informed decisions for maintaining a healthy marine environment.
Advanced ICP Testing
Building upon our Standard ICP Testing, the Advanced ICP Testing service incorporates additional analytical techniques to offer a more comprehensive assessment of your aquarium's water quality. In addition to the elements analysed in the Standard ICP Test, this service includes:
-
Ion Chromatography (IC): Measures anions such as Fluoride (F⁻), Nitrite (NO₂⁻), Nitrate (NO₃⁻), and Sulphate (SO₄²⁻).
-
Robotic Titration: Determines parameters like pH and Alkalinity.
-
Colorimetry: Assesses orthophosphate.
-
Conductometry: Measures Conductivity, salinity and Specific Gravity.
-
UV-VIS Spectrometry: Orthophosphate (PO₄³⁻)
This expanded testing capability allows for the precise measurement of additional parameters, providing a holistic view of your aquarium's health.
Our in-house SPECTROGREEN DSOI ICP-OES, combined with these advanced analytical methods, ensures that reefers receive the highest quality analysis in the industry.
ICP-MS Testing
For aquarists seeking the most detailed analysis available, our brand new Agilent ICP-MS (Inductively Coupled Plasma Mass Spectrometry) instrument offers unparalleled precision. This service encompasses all the assessments provided in the Advanced ICP Testing, with the addition of ICP-MS technology for trace and ultra-trace element detection. While ICP-OES is highly effective for measuring macro elements present in higher concentrations, ICP-MS excels in detecting trace and ultra-trace elements at parts-per-trillion (ppt) levels. This dual approach ensures comprehensive coverage of both macro and trace elements, delivering the most accurate and reliable analysis possible.
By integrating multiple analytical techniques—including ICP-OES, ICP-MS, Ion Chromatography, Robotic Titration, Colorimetry, UV-VIS Spectrometry and Conductometry—our ICP-MS Testing provides reef keepers with a complete and detailed understanding of their aquarium's water chemistry. This comprehensive insight enables proactive management and maintenance of optimal conditions for all marine inhabitants.
At Reef Zlements, we are dedicated to providing precise and reliable water testing services to support the success of your reef aquarium.
