Hach DR6000 UV-VIS Spectrophotometer with RFID

A UV-VIS laboratory spectrophotometer for comprehensive water analysis

The DR6000 is Hach’s UV-VIS laboratory spectrophotometer, described by Hach in its datasheet as the industry’s most advanced lab spectrophotometer. It combines UV and visible spectrum capability, over 250 preprogrammed methods, guided procedures and integrated quality-assurance software, and targets beverage, drinking water, industrial water, pharmaceutical, power and wastewater laboratories.

A tungsten lamp covers the visible range and a deuterium lamp the UV range, giving a wavelength range of 190 to 1100 nm with 0.1 nm resolution and high-speed scanning at 900 nm per minute in 1 nm steps. Used with TNTplus reagent vials, the instrument averages ten readings and eliminates outliers, and RFID technology updates program calibration factors automatically when a TNTplus box is placed near it.

Technical specifications

Throughput, accessories and quality assurance

A carousel sample changer allows up to seven sequential measurements, and the Sipper Module, an instrument-controlled sample delivery system, increases precision by keeping the optical characteristics constant. The instrument identifies chemistry expiration dates from the barcode on TNTplus vials and detects chemistry coefficient factors to avoid errors from lot-to-lot variations.

The integrated QA software schedules, documents and interprets quality measurements, which helps laboratories that must demonstrate control over their analytical process. The available-tests table in the datasheet lists the ranges for the supported parameters.

Where the DR6000 fits, and what to confirm

Select the DR6000 when UV measurements are required, such as spectral scans and method development, or when the laboratory wants the largest method library and the 200 user program slots. For visible-range routine testing, Hach also lists the DR3900; for field use, the DR1900.

Before ordering, confirm the methods and sample cells required, whether the carousel or Sipper accessories are needed, the mains supply and the bench space for a unit that weighs 11 kg. Hach notes that RFID technology is currently available only in the countries printed in the datasheet, and that specifications are subject to change without notice.

How the Hach DR6000 works

A spectrophotometer measures how much light a sample absorbs at a chosen wavelength. The DR6000 sends light from a tungsten lamp for the visible range and a deuterium lamp for the UV range through the sample cell. A detector measures the light that comes through, and the instrument turns the result into absorbance, transmittance or concentration. With reagent vials, the DR6000 reads the code on the vial by RFID and chooses the right program and calibration factors by itself.

Installation, commissioning and maintenance notes

Place the instrument on a stable bench away from vibration, direct sun and heat. Allow the lamps to warm up as the manual says. Run the self-check and a zero reading with a blank before the samples. Keep the cell windows clean and free of fingerprints, close the lid for each reading, and use fresh reagents. Check the instrument with standard solutions at planned intervals and log the results.

DR6000 wavelength performance

The wavelength accuracy is within 1 nm, the resolution is 0.1 nm and the spectral bandwidth is 2 nm. Scanning runs at 900 nm per minute.

DR6000 photometric range

The photometric range is plus or minus 3 absorbance units, with linearity from 0.005 to 2 absorbance.

DR6000 display and data

A 7 inch colour touchscreen shows the guided steps. The logger keeps 5000 data points with the result, the date, the time and the sample and user IDs.

DR6000 interfaces

The instrument has two USB type A ports, one USB type B port, Ethernet and an RFID module.

Laboratory records for DR6000

Keep the calibration checks, the reagent lot numbers and the lamp hours with the laboratory quality file.

Choosing the right DR6000 accessories

A carousel sample changer allows up to seven readings in sequence, which saves time on batches. The Sipper Module draws samples through the cell under instrument control, which helps with repeated tests of the same sample type.

Choosing the right cell for the DR6000

Use the 10 mm rectangular cell for most routine tests, longer cells for low concentrations, and round cells for reagent vials. Match the cell to the method and keep a spare set.
