HS-421A Fully Automatic Headspace Sample Injector

HS-421A is a stable and reliable sample pretreatment instrument that can be applied to different sample matrices

Reduce or eliminate the need for sample pre-treatment

Reduce maintenance costs for injection ports and chromatography columns

Fully automated analysis

Easy to operate

High sample carrying capacity and processing capability

Stable and reliable design

1. From daily quality control to new product research and development, provide diverse support for volatile components.

The most suitable way to meet the high reliability requirements of modern analysis is to use a stable, sturdy, and durable precision instrument.

The performance of the HS-42A fully automatic headspace sampler enables it to meet new challenges in daily analysis and provide reliable and trustworthy analysis results.

2HS-42AThe fully automatic headspace sampler has powerful sample processing capabilities

Can use 10ml20mlHeadspace bottle, meeting a large number of analytical requirements

The starting and ending bottle positions can be freely set to meet special on-site requirements.

The shaking function of the sample bottle accelerates the balance time, improves efficiency, enhances sensitivity and reproducibility;

6 sample heating positions can be overlapped for heating, saving analysis time and achieving high speed.

Automatically detect missing sample bottles to reduce confusion in sequence analysis.

3. Reliable results and reproducibility

Valve and quantitative loop technology are currently highly reliable and highly reproducible techniques in use. With fixed and known volumes of samples, precise temperature control ensures good reproducibility and avoids the risk of erroneous results and sample condensation.

All sample flow paths have undergone insulation treatment and chemical inertness treatment, which greatly reduces analytical residues and maintains the integrity of the sample.
