P100, P200, P200 II P230， Generation after generation of liquid chromatography products, nearly 20 years of struggle in the field of liquid chromatography, Dalian Yilite Analytical Instrument Co., Ltd., as a pioneer in domestic liquid chromatography products, with its solid technical foundation and excellent product quality, once again provides liquid chromatography users with a new generation of "ultra-high cost-effectiveness" liquid chromatography instrument - P1201 high-performance liquid chromatography.

This instrument fully draws on our company's years of experience in instrument production and development, coupled with the long-term production and use testing of important components, the performance is more stable, and the product is more trustworthy.

UV1201UV Visible Detector

UV1201 adopts a dual CPU system based on MSP430 microcontroller, which performs system management, signal acquisition, and data processing separately. The signal output can be directly connected to the computer through RS-232 or USB conversion interface, avoiding multiple signal conversions, making performance more stable, reducing baseline noise and drift of the detector, and improving detection sensitivity. Set the detection wavelength of the UV1201 UV visible detector to 254nm and the response time to 1.0s. Under room temperature conditions (temperature: 20 ℃, humidity: 50%), after preheating for 60 minutes, collect data and calculate the baseline noise to be ≤± 0.5 × 10^-5AU; Drift ≤ 1 × 10^-4According to the testing method of JJG705-2002 Liquid Chromatography, the minimum detection concentration (S/N=2) is 4 × 10^-9g/mL。

● Extremely high detection sensitivity

● Minimal baseline noise and drift

● Time wavelength program

P1201High pressure constant flow pump

The P1201 high-pressure constant flow pump adopts a CPU controlled reciprocating double plunger rod series pump head. Stepper motor subdivision drive, improved cam curve formula, ensures accuracy under low flow conditions, while making flow more stable. It has flow system error compensation, high and low pressure protection, and alarm functions. RS-485 external communication interface design, which can be controlled externally by a workstation, and the workstation can display various parameters during pump operation in real time.

● Stable traffic

● Extremely high gradient accuracy

● Gradient mixing is complete and the baseline is stable

Real time computer control and status feedback function

The new EC2006 chromatographic data processing workstation can achieve bidirectional data transmission. Not only can the instrument be controlled in real time through the workstation, but the workstation can also provide real-time feedback and display various status information of the instrument.

Accurate flow compensation correction function

Due to the different compressibility coefficients of different organic solvents, their flow rates may differ from the set flow rate under high pressure conditions. Through the flow compensation correction function, the flow rate can be accurately controlled to meet the needs of different users.

● Pump head online cleaning function

Regular cleaning of the pump head is essential for high-pressure constant flow pumps using mobile phases containing inorganic salts, as it can effectively reduce the probability of pump leakage. The online cleaning function of the pump head of P1201 high-pressure constant flow pump makes this operation no longer troublesome. With just a button, the pump head cleaning work can be automatically performed.

● Automatic spectral scanning function

Can help users determine the optimal measurement wavelength for the tested sample.

● Wavelength time program setting function

When analyzing multiple compounds simultaneously, because the optimal detection wavelength for each compound may not be consistent, selecting a specific wavelength for detection may result in a loss of detection sensitivity for some samples. Using wavelength time programs to detect different samples at their optimal detection wavelengths can effectively improve the detection sensitivity of various compounds.

New design, stylish appearance

Adopting VFD high brightness vacuum fluorescence display, the instrument panel made of high-performance materials in the United States is manufactured through molds, which not only has a more beautiful appearance, but also is resistant to corrosion from various solvents, making your experiments worry free. Humanized structure and button design make operation more convenient.

EC2006Chromatographic data processing workstation

EC2006 chromatographic data processing software is a 32-bit completely independent application based on the Windows 98/2000/XP operating platform. It adopts the latest software design technology (O-O technology) and can comprehensively control the instrument and provide real-time feedback on its status, making its functions more powerful. The new interface design of EC2006 chromatographic data processing software is beautiful, concise, easy to learn and use.
