HP 1050 G1306A Diode Array Detector (DAD)

Detection Type

Double beam photometer


Up to 3 (MWD) or 5 (DAD), each defined by a sample wavelength and bandwidth and an optional reference wavelength and bandwidth.

Signal Combinations

Sum of two signals; difference of two signals; ratio of two signals, with definable range and threshold; window plot with definable ratio, range and threshold.


< ±2.0 x 10-5 AU peak-to-peak, at 254 nm with 4 nm bandwidth, flowing water at 1 ml/min, 1 second response time (10-90%).


< 2 x 10-3 AU/hour, at 254 nm, after warm-up

Wavelength Range

190-600 nm, selectable in 1 nm increments

Bandwidth Range

2-400 nm, selectable in 1 nm increments.

Wavelength Accuracy

±1 nm.

Linear Absorbance Range

Better than 1% up to 1.5 AU, using acetone at 265 nm.

Response Time

8 choices, ranging from 0.1 to 20 seconds (10-90%).


Storage of at least 8 spectra, with definable wavelength range from 190-600 nm (total number of spectra depends on range defined). Post-run plotting of original or subtracted spectra possible

Spectra Resolution

Depends on slit width.

Absorbance Resolution

< 5 x 10-6 AU

Spectra Acquisition

12.5 ms from 190 to 600 nm; according to the response time settings scans are accumulated for one data point for improved sensitivity.

Light Source

Deuterium lamp.

Flow Cell (Series II)

SST cell, 8 µl volume with 6 mm path length or 13 µl volume with 10 mm path length and 120 bar (1760 psi) maximum pressure. Optional high-pressure cells

(400 bar).


2 line by 16 character fluorescent display with real-time display of operating parameters or absorbance and wavelength of maximum absorbance.


Integrated keyboard with function keys; parameter editing during run possible; keyboard lock. External control via GPIB with ChemStation or RS-232.Integrated keyboard with function keys; limited functionality and control on DAD.


Signal definitions (wavelengths/bandwidths),

attenuation, response time, zero offset, balance; spectra definitions; external contacts; analog outputs.



Wavelengths/bandwidths, attenuation, spectra acquisition, external contacts


Battery-backed storage of up to ten methods (depends on length of method), including initial and time-programmed parameters. Automatic startup and shutdown methods. Editing of stored methods possible during run.

Analog Outputs

Two analog outputs are available (on DAD optional) for output of signals and/or signal combinations; both

1 V/2 AU or 100 mV/2 AU, user selectable.


START (in- and output), STOP (in- and output), READY (output), SHUTDOWN (output) for synchronization with other LC modules; two external contacts

including: 1 relay with 24 V and 250 mA; 1 contact closure with maximum 30 V and 250 mA.

Safety Aids

Extensive diagnostics, error detection and display via front-panel LED’s and status logbook. User-definable shutdown method activated in case of error. Leak

detection, safe leak handling, leak output signal to shutdown the pump


Temperature range: 5 to 55 °C

Humidity: < 85% (non-condensing)

Power Requirements

Line voltage: 100-120 or 220-240 VAC ±10%Line frequency: 48-66 Hz

Power consumption: 150 VA max
