Spectrally™ places a Raman probe directly into your ATS, KTS/CaTS, and AMS stream — inline, meaning within the absorption stream, pipeline, or tank itself, with no sampling required. Thiosulfate concentration, N/S ratio, and solution homogeneity are measured in seconds, continuously, without reagents, replacing the 20- to 60-minute wait for iodometric titration or ion chromatography.

Ammonium, potassium, and calcium thiosulfate, plus ammonium sulfate — the aqueous sulfur-fertilizer streams produced by gas absorption.
Master variable
Thiosulfate concentration & N/S ratio
The parameters that define the product — read in real time rather than inferred after the batch.
Reference technique
Raman spectroscopy
Thiosulfate and sulfate are strong Raman-active oxyanions, and water is a weak Raman scatterer — so Raman measures them cleanly inline.
Where it sits
In the absorption stream, 24/7
An immersion probe in the absorption stream, pipeline, or tank, continuously feeding your PLC / DCS.
01Inside this mini-site
Everything a sulfur-fertilizer plant asks us — one page per answer.
Six focused pages: the chemistries we cover, the parameters we read, how the measurement works, the technical rationale behind it, the regulatory context, and the instrument itself.
Iodometric thiosulfate titration yields results in 20 to 30 minutes; full anion analysis by ion chromatography takes 30 to 60 minutes; densitometry serves only as a concentration proxy and never reveals composition. The absorption process runs continuously, so by the time the result is available, the stream has moved on.
Offline lab loop
20-60min
Sample, walk to the lab, run iodometric titration or ion chromatography, wait, report. A deviation in thiosulfate concentration or N/S ratio only surfaces as an off-spec delivery at your customer — after the product has shipped, where it becomes a complaint and a CE-certification issue.
Spectrally inline
< 5s
The probe reads the absorption stream, pipeline, or tank continuously and streams thiosulfate concentration, N/S ratio, and homogeneity to your control system. The deviation is caught while you can still correct it — so titration and ion chromatography become verification, not the bottleneck.

Your next step
Put it on your stream — starting with your own samples.
Send representative samples or process data from your ATS, KTS/CaTS, or AMS stream. We build and validate a chemometric model on your matrix and show you exactly what inline Raman would read on your line — before any commitment. Your feasibility study puts the numbers on the table: the validated model and the figures for your own material.
