Yilite P1201 liquid chromatography instrument

UV1201 UV 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 ^ 2^-9g/mL。

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 * measurement wavelength of the tested sample.

● Wavelength time program setting function

When analyzing multiple compounds simultaneously, because the detection wavelength of each compound may not be the same, 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 detection wavelengths can effectively improve the detection sensitivity of various compounds.
