IQ-LabLink – the link to the world of online instrumentation

IQ-LabLink enables a save data exchange between the IQ SENSOR NET and the laboratory instrument. The exchange is processed via a common USB memory stick, serving as data medium between the Online system and the laboratory instrument. The condition is that both instruments feature this function and are equipped with a USB interface. The first WTW instruments to include this function are the two new spectrophotometers photoLab® 6100 VIS and photoLab® 6600 UV-VIS (laboratory instruments) and the terminal/controller MIQ/TC 2020 XT with access to the IQ SENSOR NET.

Analytical Quality Assurance (AQA) – From self monitoring to large laboratory environment

  • Extensive equipment testing
  • MatrixCheck
  • Extended user administration

The instrument supported Analytical Quality Assurance has become a must across all industries to guarantee plausible and correct measuring results. The photoLab® 6000 series supports the AQA for checking the instrument and for individual routine measurements. The administration of user groups for large laboratory environments including administrative, user and guest profiles is also supported. The AQA feature can be switched on or off.

Calibration intervals for instrument and test kits

  • PhotoCheck: Instrument check including linearity at 3 wavelengths and 4 measuring points
  • Grey filter and UV-VIS test standards
  • Standards for single parameters and combined checks
  • Matrix check with spiking

Data management with USB

  • Measurement data, spectra, and kinetics
  • Software and method updates

photoLab® 6000 series is equipped with three interfaces: USB-A to connect printer, barcode reader and USB stick, USB-B for PC-connection and an RS 232 interface. Thus, the data exchange via USB is extremely convenient.

photoLab® 6000 series en-route – convenient portable operation

A spectrophotometer is typically used in the laboratory, although it is convenient when it can also be operated on-site. For on-site use, it is important to have safe transport, a sheltered area and a corresponding measuring preparation with warm up period and zeroing after transport. The light-weight and easy-to-operate photoLab® 6000 series is flexible when on-site operation is required. A sturdy carrying case, and a 12 V adapter cable for connection to a typical car battery are available options.
