Autosampler Specifications
Minimization of sample diffusion - Optimum for semi-microcolumn analysis!
Autosampler
Optimized for Biological Samples
Sample Cooling Function
The autosampler features a sample cooling function, useful for analysis of biological samples.
Metal-free Structure
The flow channels are made of polyetheretherketone (PEEK) resin, allowing analysis of samples of strong adsorptive nature, such as proteins or other physiologically active samples.
Pre-column Labeling Function
Pre-labeling function
(OPA labeling of amino acids)
Selection of Sample Vials
Vial Holder
(1) 96-Well Microplate
(2) Conventional Vial
(3) Osaka Soda Vial (100 Samples)
(4) Osaka Soda Vial (200 Samples)

 *Osaka Soda vials are available in 50 µL and 250 µL types.
Complete Rinsing System
A complete rinsing system is adopted for the sampling mechanism to eliminate contamination and carryover.
Double injection rinsing function
The sample loop and tubing are rinsed.
Post-injection rinsing function
Rinsing liquid can be chosen from any positions.
Syringe, needle, injection port, and injection valve are rinsed.
System configuration with double-injection rinsing function
High-precision Analysis at High Sensitivity
Small Dead Volume Structure
The capacity of the injection valve has been reduced to 1.9 µL, virtually eliminating diffusion of the sample. Semi-microcolumns of 1.0-mm I.D. are also available.
Influence of dead volume on semi-microcolumn HPLC
Comparison of Peak Efficiency of Standard Compound (naphthalene) between Nanospace and Conventional Instrument (Retention time: 12 min)
High Precision and Endurance
High precision is maintained even at small injection volumes (RSD less than 1% at 1 µL injection). A minute injection of 100 nL is also possible. The standard sampling volume ranges from 0.1 to 80.0 µL.
 *Up to 400 µL injection can be made by using multiple collection injection.
Efficient Sampling System
Polypropylene (PP) sample vials (50 µL & 250 µL) are suitable for biological samples. Valuable samples will not be wasted.
 50 µL vial: Minimum required sample volume = Injection volume + 2 µL
Easy Operation with Key Pad
Programming is set by using the numerical key pad.
Networked System Control
Remote operation from a Windows™ PC is possible.
