Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Concentration-Discharge Relationships of Dissolved Rhenium in Alpine Catchments Reveal Its Use as a Tracer of Oxidative Weathering (2021), Water Resources Research. Implementations in other papers (listed below) may differ.

1. River water sample collection in Swiss catchments
   River water samples were collected weekly by hand, lowering a 1L bottle into the channel just above the gauging station installation. Samples were collected between 02/08/2011 and 16/07/2012.
   Quantities: 29 samples total from Erlenbach, 25 samples from VogelbachDuration: Weekly sampling for approximately 11 monthsConditions: Various flow conditions from baseflow to high discharge events
   Equipment: 1L bottles, gauging station
2. Sample filtration and preservation for Swiss samples
   River water samples were filtered through an acid-cleaned Nalgene vacuum filtration tower operated by a hand pump. Nylon filters of 0.2 μm pore and 47 mm diameter were used and filtered water was collected into pre-acid-cleaned bottles.
   Quantities: ~250 ml collected per sample for major cations and trace elements, 60 ml for anion analysisDuration: Immediate processing after collectionConditions: Acidified to pH ~ 2 with trace element analysis grade HNO₃
   Equipment: Nalgene vacuum filtration tower, hand pump, 0.2 μm nylon filters, 47 mm diameter filters, pre-acid-cleaned bottles, trace element grade HNO₃
3. Automated water sampling in East River
   Water samples were collected using an automatic water sampler (Model 3700; Teledyne ISCO, NE, USA). A peristaltic pump sampled water from the main stream into 1 L polyethylene bottles and was retrieved at regular intervals.
