QUANTOFIX Nitrate/Nitrite

QUANTOFIX Nitrate/Nitrite is a semi-quantitative test-strip system for simultaneous visual assessment of nitrate and nitrite in aqueous samples. The sticks measure 6 × 95 mm and provide two graduated scales: 0–10–25–50–100–250–500 mg/L NO3⁻ and 0–1–5–10–20–40–80 mg/L NO2⁻, enabling clear colour-chart comparison without laboratory instruments. Each pack supplies 100 determinations, supporting frequent screening in environmental analysis, water quality checks and routine laboratory monitoring where both nitrogen species must be tracked. Offered as a ready-to-use QUANTOFIX kit from manufacturer Macherey-Nagel, the format is designed for simple dip-and-read handling in field or bench settings. Distinct concentration steps across the nitrate and nitrite ranges help users classify samples from low background levels through elevated loads in a single workflow. Compact packaging keeps the full determination set organised for repeated use in wastewater surveys, process control and general laboratory screening programmes that require reliable dual-parameter strip testing.
