autosampler

Qingdao ShenghanautosamplerSHA-11

SHA-11 single channel

● 2mL x 120 bit sample

● Full quantitative ring injection

● Seven inch color LCD display screen

● Fully open transparent design, allowing every subtle mechanical movement to be fully visible
● Fully computer-controlled, all operations can be achieved through computer software, and compatible with any liquid chromatography both domestically and internationally
● Long service life of vulnerable parts
The metering pump with a gemstone rod as the plunger rod is designed for liquid suction, and its high-pressure sealing ring has a service life of over 1 million times, which is 10-20 times longer than the service life of similar products. It can also ensure continuous use of the whole machine for 3 to 5 years without the need to replace vulnerable parts
Design of injection needle for ● *
Unlike traditional injection needles, this injection needle adopts a side hole injection method. The injection hole is not located at the top of the injection hole tip, but a small hole is opened on the side to effectively prevent plastic particles from entering the sample needle. In addition, micro holes are opened on both sides of the sample needle to prevent bubbles from being generated during liquid extraction
● *'s self-protection function
Qingdao ShenghanautosamplerSHA-11 has adopted multiple technologies in its design and development, equipped with multiple protective measures to minimize damage to the automatic sampler caused by improper operation.
1. Pressure sensors,
Monitor and detect pressure changes in the pipeline at all times. When the sampling needle is blocked, it can stop running in a timely manner and sound an alarm, effectively preventing unpredictable faults caused by pipeline blockage.
2. Missing bottle sensor
In order to avoid operator errors affecting the normal operation of the instrument or damaging the instrument, a missing bottle sensor is configured. When the bottle holder of the instrument cannot detect the sample bottle, the system will automatically prompt to stop sampling or skip this position to collect the next sample bottle

3. Top pin sensor
When the injection needle detects hard objects on the sample tray or inverted sample bottles, and the injection needle cannot be inserted smoothly, it will automatically lift to avoid damage to the injection needle caused by misoperation

4. Leakage sensor
Mainly monitor the leakage of the injection valve to avoid inaccurate injection caused by leakage
● Comprehensive self diagnosis and recording functions
1. Quick self check upon startup, rapid positioning and calibration of each coordinate axis, and detection of the working status of the metering pump
2. Record of usage frequency of high-pressure flow valve
3. Record of sealing ring usage times
4. Record of usage frequency of metering pump valve core
