Overview
The Hach DR 3900 is a benchtop visible spectrum (320-1100 nm) split beam spectrophotometer with over 220 pre-programmed methods optimized for laboratory water analysis. The DR3900 spectrophotometer is optimized for safe processes and accurate results daily. Control parameters like Ammonium, COD, Phosphate, Nitrate and many others are easy to test.

Simple Preparation
NTplus® vials use Dosicaps - freeze-dried reagents integrated into a sealed cap - that are easier to use than Powder Pillows or Liquid Reagents, without any risk of contamination. The boxes and vials are color-coded for fast and easy parameter and range recognition of the test needed. Step-by-step illustrated test methods are printed on the box as a quick reference and can also be called up in the instrument menu.

Comprehensive Documentation
Measurement results are documented on a detailed level with a timestamp, operator ID, absorbance reading, and calculated concentration. The 2D barcode delivers the lot number and expiry date, logged with every result. For accreditation, the certificate of analysis can be called up just by wiping the reagent box towards the RFID sensor.

Fast Execution
The Hach DR 3900 spectrophotometer automatically reads a 2D barcode on the TNTplus vial to identify the appropriate method and take the measurement. The vial spins to take 10-fold absorbance readings that will be averaged for result determination to exclude scratches and fingerprints. Instrument calibration verification and high instrument stability all combine to eliminate the need to run reagent blanks.

Customizable
With the ability to store hundreds of user-determined methods, operators are able to tailor the DR 3900 to meet the everyday needs of the facility. Optimizing and customizing the method portfolio, combined with regular software updates and Claros™ connectivity, makes the DR3900 the ultimate solution to water quality lab needs.

Questions & Answers
What is the procedure for phosphate testing using the high range reactive phosphate 0 - 100mg/l reagent set (SKU 2767345)?
The Hach DR3900 can measure high-range phosphates in water samples using the reagent set and the Molybdovanadate Test 'N Tube™ Method (Hach Method 8114), found in the documents tab on the reagent product page.
Are you able to determine any amount of cyanide above 5ppm in both potable and wastewater using the Hach DR3900 Laboratory VIS Spectrophotometer?
No. The DR3900 can only measure cyanide in the range of 0.01 - 0.6 mg/L CN (TNTplus) or 0.002 - 0.240 mg/L CN- (Hach Method 8027).

Poás Volcano Gives a Glimpse of Life on Mars

To get an idea of what life would be like on Mars, you don’t need to travel millions of miles away--instead, you could go to Costa Rica and visit the Poás Volcano and its crater lake, Laguna Caliente. “Collectively, the suite of alteration minerals at Poás crater and identified across Mars at relict hydrothermal sites shows strong correlation, indicating the high temperature and highly acidic geochemical processes occurring at Poás are quite relevant to understanding past hydrothermal processes on Mars,” says Justin Wang, a graduate student at the University of Colorado, Boulder. He is currently conducting research at the Laboratory for Atmospheric and Space Physics alongside his advisor, Brian Hynek. Wang is currently a master's student in aerospace engineering.

Combating Water Insecurity in Saskatchewan with Real-Time Data

The prairies of Saskatchewan can be described as one of the least water-secure parts of Canada, making water quality monitoring essential for informed resource management in a region already facing water insecurity. While natural physical properties worsen some of the poor water quality conditions in the region, others are connected to land use. Having grown up spending summers on the shores of Lake Huron, Helen Baulch, an associate professor at the School of Environment and Sustainability at the University of Saskatchewan , has always been dedicated to the protection of water resources. Looking back fondly at her childhood playing along the shore, Baulch also recalls the invasion of quagga mussels during her teenage years and watching the lake change as a result.

Seametrics Turbo Turbidity Logger: Boost your Turbidity Monitoring

The Seametrics Turbo Turbidity Logger is a self-cleaning turbidity sensor capable of internally logging over 260,000 data records. The sensor enables researchers, compliance officers, and contractors to monitor turbidity in various applications, from construction and dredging sites to wastewater effluent.  Due to its narrow width, this device can be deployed in a range of areas, from small well spaces to rivers and streams. The stainless steel housing and built-in wiper allow the sensor to withstand long-term deployments and reduce the need for maintenance trips.  The logger accurately records temperature and turbidity up to a depth of 50 meters.
