Physical specification parameters

Project specifications

The size of the host is not directly specified. Referring to the design of similar horizontal heating graphite furnace models, it is estimated to be about 800 × 500 × 450mm (length × width × height)

The weight of the entire machine is not clearly indicated. Considering the structure of the transverse heating graphite furnace and the automatic sampling module, it is estimated to be 70-90kg

Key Explanation

Structural feature evidence:

Adopting a transverse heating graphite furnace system (different from longitudinal heating), this design is usually more compact and has a smaller volume than traditional longitudinal heating models;

Support the combination of SPS-5 automatic sampler and SIPS-10 injection diluter, resulting in a significant increase in volume and weight after expansion.

Installation requirements:

Special graphite tubes (horizontal heating platform type) and cooling systems need to be configured, occupying additional space;

The load-bearing capacity of the workbench should be ≥ 100kg, and a maintenance channel of ≥ 50cm should be reserved around it.

Parameter missing explanation:

The search results did not provide direct size data, and the above inference is based on:

Optimization characteristics of lateral heating technology on volume;

The weight range of similar atomic absorption spectrometers (such as SpectraA-Duo220FS).

Note: It is strongly recommended to refer to the actual equipment or manufacturer's technical manual. Actual parameters may vary due to configuration (such as whether automatic sampler or cooling module is included).

Physical parameters

Project Description

The size is not clear, and the transverse heating structure design is compact (referring to similar models)

The estimated weight is around 70-90kg (including graphite furnace module)

Installation requirements include a load-bearing platform (≥ 100kg), shock-absorbing environment, and external acetylene/air source

Key Explanation

Scalability:

The SIPS-10 injection dilution instrument can automatically process high concentration samples;

The SPS-5 automatic sampler supports batch testing (with reserved operating space).

Consumables:

Special horizontal heating platform graphite tube (LTT-HP or LTT-HGO type) is required;

The flame method requires high-purity acetylene (≥ 99.8%).

Application scenarios:

Suitable for water bodies (such as chromium detection in wastewater) and trace analysis of biological samples;

The graphite furnace method is more suitable for detecting ultra trace elements such as cadmium and lead.

Note: The physical parameters are inferred values for similar models, and the actual equipment shall prevail; There are slight differences in the detection limit data, which may be due to different testing conditions.
