1direct reading spectrometerCore principles of selection

Based on the selection of "matching detection requirements, meeting accuracy standards, and being stable and durable", taking into account the adaptability of usage scenarios and post operation and maintenance costs, to ensure that the instrument can efficiently complete element analysis tasks.

2、 Key selection points

Clarify the detection elements and scope: Based on the requirements, confirm the types of elements (such as metals and non metals) and their content ranges to be detected, and select the model with corresponding detection capabilities.

Confirm accuracy and resolution: Select instruments with small detection errors and high resolution according to industry standards, and pay attention to long-term stability in high demand scenarios.

Matching sample types: Spark direct reading spectrometer is preferred for metal samples, while ICP direct reading spectrometer can be considered for liquid/powder samples. The sample morphology should be clarified before selection.

Considering usage scenarios: For laboratory fixed testing, desktop high-power models are available. For on-site rapid testing, portable models are preferred. In harsh environments, attention should be paid to the level of protection.

Pay attention to operation and data functions: batch testing is required to select automatic sample feeding models, and data tracing is required to select models with storage and export functions to reduce operational complexity.

Evaluate after-sales and consumables: Choose products with multiple brand service outlets and convenient calibration, while paying attention to the accessibility and cost of consumables such as electrodes and argon gas.

Avoid blindly pursuing multi-element detection: there is no need to pay additional costs for non essential elements, just focus on core detection needs.

Do not ignore the difficulty of sample processing: Some instruments have requirements for sample shape and size, and before selecting, it is necessary to confirm whether the sample is suitable.

Pay attention to the operating costs of instruments: In addition to the purchase price, long-term costs such as argon gas consumption, consumables replacement, calibration and maintenance need to be accounted for.
