Module lineup

Pump

5110：Pressure withstand 40 MPa / 5160：Pressure withstand 60 MPa

Compatible with multiple HPLC to UHPLC Entry-level model

In addition to the traditional 40 configuration MPa Outside the system, Chromaster PLUS It can also be configured to support 60 MPa System's 5160 pump and 5260 /5280Automatic sampler.
60MPa The system can choose particle size 2.0 μm The following columns and core-shell columns not only support conventional HPLC Analysis can also effectively improve separation performance and shorten analysis time.

Excellent liquid delivery performance

Hitachi's specially developed 5110 /5160The pump, its high-speed feedback real-time control system can provide high-precision liquid delivery, while the proportional valve high-frequency mode ( HFM: High Frequency Mode） Excellent gradient performance can be provided, thereby achieving high reproducibility of retention time.Pump options

Automatic sampler

5260：Pressure withstand 60 MPa、 Quantitative ring injection / 5280：Pressure withstand 60 MPa、 Direct sample injection

Excellent injection volume reproducibility

Both the quantitative ring injection and direct injection use high-precision syringe and syringe driving unit, which can improve the syringe metering accuracy and achieve better injection volume reproducibility.

Very low sample residue

The automatic sampler has been completely upgraded to achieve extremely low sample residue by improving the pipeline connection method and inlet structure, whether it is the quantitative ring injection method or the direct injection method.

Column thermostat

5310： level / 6310： vertical

Easy to accommodate 300 with protective posts mm Analytical column

Internal dimensions 375 wide mm， High 114 mm， The column thermostat can hold up to 3 300 pieces mm Chromatographic column. The chromatographic column has a spacious installation space, and although it has an air circulation system, it can also be easily installed and disassembled.

Standard preheating function and wider temperature control range

The preheating modules in standard configuration are based on Palte heating /The refrigeration control function greatly improves peak symmetry and sharpness. (There are preheating pipes for suitable flow rates to choose from. )
In addition, the temperature control range of column thermostat is (room temperature-15 ℃）To (room temperature +60℃）（Temperature setting range: 1 ～85℃），Can meet various application needs。

Optional valve for sample pretreatment and method evaluation

In applications such as automatic sample pretreatment (such as protein removal), method development, and other applications, two-position six-way valves or 3-column selection valves can be selected.

Detector

5410/5420 UV /UV-visible light detector

Low noise, low drift, high sensitivity detection

Noise value 0.4 ×10^-5AU（ Under specified conditions), the detection sensitivity is improved.
Drift value 1.0 ×10^-4AU/h（ Under specified conditions), ensure a more stable baseline.

Dual wavelength simultaneous detection function

Dual wavelength detection function^*1Can be achieved under shorter data acquisition intervals, and the data acquisition interval for each wavelength can be set to (800 ms， Even 400 ms^*2）To obtain a sharper peak shape chromatogram.

*1：Only through CDS Control to implement

*2：400 ms Only at double wavelength intervals are 160 nm Use under the following conditions

5430 Diode array detector

High qualitative analysis ability

Wide wavelength range （190 - 900 nm） and high spectral resolution (with 1024-bit diode) Chromaster PLUS Diode array detectors are committed to creating high-level high-resolution analysis.

Lower noise, lower drift

5430The noise value of the diode array detector is comparable to that of the ultraviolet detector. ≤0.5×10^-5AU^*，Supports high sensitivity detection.
Use an adjustable air volume fan and a special cover plate on the optical splitter greatly reduces the impact caused by temperature changes around the optical system, thereby further reducing drift. The index is ≤0.4×10^-3AU/hr^*，At the same time, the preheating and stabilization time of the lamp is shortened by 30% (compared with the old product models of our company).

5440 Fluorescence detector

Raman spectrum of water S/N ≥3000High sensitivity

The detector is equipped with an optical system with small light energy loss. Its distinctive features are: three-dimensional optical axis configuration optical design, Hitachi specially developed condenser, small volume flow cell and optimized transmitted light monitoring technology. This is a Raman spectrum of water S/N ≥ 3000（baseline method) high sensitivity fluorescence detector.

Fluorescence detector for variable slits

Emitting light monochromator slit can be at 15 nm and 30 nm Switch between, 30 nm Slits can be used for high sensitivity analysis.

Constant temperature flow cell (optional)

It is equipped with a constant temperature flow cell that reduces the impact of room temperature changes. This flow cell can be used when measurements are required at fixed and stable sensitivity.

5450 Differential refractive ( RI） Detector

Short preheating time

After turning on the power supply, the differential refractive detector can start the measurement in about 1 hour.

The flow cell temperature is adjustable

The temperature of the flow cell can be set to 30 ~50℃Any temperature between (1 ℃Stepping) (room temperature is 20 ℃）。

Organizer

Multiple solvent bottles can be placed
Can be used as a power supply module

The organizer is also a power supply module, including 1 pump, 1 automatic sampler, 1 detector (1 UV detector, 1 UV-visible detector, 1 diode array detector, or 1 differential refractive detector)) and 1 block IFC The interface board is powered.
