As a new autosampler for Chromaster series, we have developed 5280 autosampler, an instrument that adopts the direct-injection method with a pressure rating of 60 MPa.
In addition, we have newly released ChromasterUltra Rs 6310 column oven - a part of ChromasterUltra Rs lineup- for use with Chromaster system.

Key features of 5280 autosampler

  1. Direct-injection architecture
    The adoption of the direct-injection architecture allows a tiny volume of the sample to be injected with no loss.
    5280 autosampler can be connected to other instruments in Chromaster series to allow use as a conventional liquid chromatography.
  2. 60 MPa pressure rating
    60 MPa pressure rating allows the use of columns with particle sizes of 2 µm or less, as well as core-shell columns. This improves separation performance and reduces analysis times.

Key features of 6310 column oven

  1. Wide temperature control range
    6310 column oven uses Peltier temperature-control method, allowing the temperature to be controlled over a wide range of room temperatures -15 to +75°C. With a temperature-setting range of 4-90°C, the instrument allows the collection of application data at a temperature of 85°C or above, a region that was difficult to control using the previous-generation 5310 column oven.
  2. Outstanding temperature-increase/cooling times
    The time required to raise the temperature from a room temperature of 25 to 40°C is only 4 minutes. With significantly improved heating and cooling power, there is no need to wait long periods of time for the instrument to reach the desired temperature, reducing system startup time.
