Sodium naphthionate is a fluorescent tracer used to study water circulation in natural environments. It can help identify a hydraulic connection, monitor an underground flow path or distinguish between several water inputs during the same study. It is also a useful option in protocols involving several tracers, particularly when different injection points, flow paths or recovery areas need to be distinguished. Fluotechnik supports consulting firms, laboratories, hydrogeologists and local authorities working on aquifers, rivers, springs, karst networks, catchment areas and other complex hydrological systems.
Monitor water circulation and analyse the relationships between injection and recovery points.
Distinguish between several injections, flow paths or observation areas within a structured protocol.
Study aquifers, rivers, springs, karst networks, catchment areas and complex hydrological systems.
Compare sodium naphthionate with sodium fluorescein, eosin, Rhodamine WT, Sulforhodamine B or Amino G Acid.
Fluotechnik helps you select a substance that is compatible with your objective, analytical method and measurement equipment.
Sodium naphthionate makes it possible to monitor the movement of water through a natural environment using its fluorescent signal. After injection, its presence can be investigated at different observation points in order to study the relationships between several areas of a hydrological system.
It can be used to:
In karst networks, aquifers and complex catchment areas, a single substance may not be sufficient to distinguish all the flows being studied. Using several tracers can then help separate the signals and provide a better understanding of how the system operates. Sodium naphthionate can therefore complement other fluorescent substances, provided that the protocol, analytical methods and equipment can clearly identify each signal. It is particularly relevant to consulting firms, hydrogeologists, laboratories, research organisations, local authorities and professionals studying water circulation in natural environments.
Fluotechnik offers a wide range of fluorescent tracers, technical dyes and measurement equipment dedicated to hydrological tracing and natural environment studies. Sodium fluorescein / uranine, Rhodamine WT, Sulforhodamine, Tinopal CBS-X, sodium naphthionate and multi-tracer solutions allow us to meet a wide variety of flow monitoring, dispersion testing and water circulation analysis protocols. Thanks to this complete range of products and detection equipment, professionals can select the most suitable solution according to the environment being studied, the measurement method used and the level of precision required for hydrological, environmental or hydraulic studies.
Choosing a tracer does not depend solely on its fluorescence. It must also be consistent with the environment being studied, the other substances used, the measurement method and the scientific or technical objectives of the study. Fluotechnik supports professionals in selecting tracers and equipment suited to hydrological and hydrogeological tests.
Sodium naphthionate can be used to analyse water circulation in different hydrological and hydrogeological systems.
It can complement a test when several injections, catchment areas, flow paths or recovery zones need to be distinguished.
It can contribute to the study of hydraulic connections, flows, transit times and tracer recovery.
Fluotechnik also offers sodium fluorescein, eosin, Rhodamine WT, Sulforhodamine B and Amino G Acid.
Fluorimeters and data logging systems can complement the protocol according to the selected detection method.
Our team helps you compare the available substances and identify the solution most consistent with your site and analytical resources.

Sodium naphthionate is a fluorescent substance that can be used as a tracer in hydrological and hydrogeological studies. Its signal makes it possible to detect and monitor its movement through water using a suitable detection method.
It can be used to monitor a flow, identify a hydraulic connection, observe tracer recovery, study transit time or distinguish between several water circulation paths.
It can be incorporated into studies involving aquifers, rivers, springs, karst networks, catchment areas and other natural systems in which water circulation needs to be investigated.
Yes. Its detection is based on a fluorescent signal that must be measured or analysed using a suitable method.
Sodium fluorescein, also known as uranine, is one of the best-known tracers used in hydrology. Sodium naphthionate may be selected as a complementary substance, particularly when a protocol requires several distinct fluorescent signatures.
Yes, it can be incorporated into a multi-tracer protocol. However, the different substances must be clearly distinguishable during measurement and analysis.
The choice depends on the environment being studied, the required signal, expected dilution, available equipment, other tracers being used and the objectives of the test.
Monitoring a fluorescent tracer requires a suitable detection method. Depending on the protocol, this may involve sampling, laboratory analysis, a fluorimeter or other measurement equipment.
A sodium naphthionate tracing study should not rely solely on observation with the naked eye. The choice and interpretation of the signal depend on the analytical method defined in the protocol.
The quantity depends on the flow rate, volume, distance, expected dilution, measurement sensitivity and required signal level. It must be defined according to the specific conditions of the study.
Sodium naphthionate may be selected when a test needs to monitor water circulation, identify a connection between several points or distinguish between different flow paths. It can be particularly useful when several tracers are used during the same study. In this case, each substance must produce a sufficiently identifiable signal to allow clear interpretation of the recovery data.
The choice mainly depends on:
Sodium naphthionate is therefore not an automatic solution for every tracing test. Its relevance must be assessed in relation to the full protocol and the other substances that may be considered. Fluotechnik supports you in making this comparison and also offers complementary tracers, fluorimeters and data logging systems for monitoring tracer recovery.
The choice of tracer depends on the site, expected dilution, measurement method and other substances used. Compare the different Fluotechnik solutions to build a protocol suited to your hydrological, hydrogeological or environmental study.
