Frequently Asked Question
1: How does manual/automatic waste discharge affect throughput and safety in routine lab workflows?
The Semi-automatic Kjeldahl Analyzer FM-SKA-A100 offers both discharge modes, allowing labs to adapt based on workload. Automatic discharge increases throughput in high-volume settings, while manual control ensures safe handling of sensitive or reactive samples.
2: What advantages does the 10-inch touchscreen offer beyond display size?
In the FM-SKA-A100 model, the large touchscreen enhances user interaction by enabling multi-step control, faster navigation, and traceable operation logs—critical for maintaining compliance in regulated lab environments.
3: How does the system reduce data integrity risks during nitrogen-to-protein conversions?
The FM-SKA-A100 includes a built-in protein coefficient table that automates conversion calculations. This reduces manual entry errors and ensures all results are logged accurately for GLP-compliant traceability.
4: In what scenarios would steam flow adjustment be critical for result accuracy?
Steam flow control in the FM-SKA-A100 is essential when testing complex matrices like viscous food samples or high-fat feed. It prevents distillation errors by allowing precise modulation, ensuring reproducibility.
5: How does the post-analysis auto-cleaning feature impact long-term operational consistency?
The FM-SKA-A100’s automatic alkali pipeline cleaning prevents crystallization and clogging, ensuring continuous reagent flow and minimizing maintenance interruptions over extended use.
