Spectroscopy Workflow
OVERVIEW End-to-End Spectroscopy Workflow
Typical spectroscopy workflows (e.g., AA, ICP‑OES, ICP‑MS, UV‑Vis) follow the same high‑level stages regardless of sampling method:
- Sample preparation
- Sample introduction
- Measurement and data acquisition
- Rinse / washout
- Data review and reporting
Automation primarily impacts sample introduction, rinse, and sequencing, while upstream chemistry remains unchanged.
Sample Preparation
Whether sampling is performed manually or automated, sample preparation within the spectroscopy workflow involve sample digestion, dilution or filtration performed off-line, with standards and QC samples prepared manually.
AIM Autosamplers are designed for sequential processing of large sample numbers with controlled probe motion and compact footprints.
SAMPLE INTRODUCTION
Manual Sampling Workflow
- Analyst manually positions each sample
- Probe or uptake line inserted by hand
- Timing and consistency depend on operator technique
- Instrument idle time between samples is common
Implications
- Higher variability between operators
- Increased analyst workload
- Practical for low sample counts or ad-hoc testing
SAMPLE INTRODUCTION
AIM Autosampler Workflow
- Samples loaded into racks or trays
- Autosampler sequentially presents samples to the instrument
- Probe movement, depth and timing are software-controlled
- Consistent positioning and uptake across all samples
Implications
- Improved repeatability and consistency
- Reduced manual handling and contamination risk
- Enables unattended or overnight operation
MEASUREMENT & DATA ACQUISITION
Manual
- Analyst initiates each run
- Results reviewed intermittently
MEASUREMENT & DATA ACQUISITION
AIM Autosampler
- Pre-defined sequences run automatically
- Continuous, repeatable acquisition
- Compatible with routine spectroscopy workflows where sample order and timing are fixed
Automation supports higher throughput by minimizing non‑productive time between analyses.
RINSE AND CARRYOVER CONTROL
Manual
- Rinsing steps depend on operator discipline
- Higher risk of inconsistent washout
RINSE AND CARRYOVER CONTROL
AIM Autosampler
- Programmed rinse cycles between samples
- Controlled probe travel reduces carryover risk
- Shorter probe line lengths support faster washout compared to some manual setups
DATA REVIEW AND REPORTING
Manual
- Results reviewed after each run or batch
- Slower turnaround for large sample sets
DATA REVIEW AND REPORTING
AIM Autosampler
- Full batch completed before review
- Consistent datasets support trending and QC analysis
Comparison
| Aspect | Manual Sampling | AIM Autosampler |
| Throughput | Low-Moderate | Moderate-High |
| Repeatability | Operator-dependent | High, programmed |
| Analyst Time | High | Reduced |
| Scalability | Limited | Designed for batch processing |
| Unattended Operation | No | Yes |
Applications of Choice
Autosamplers are commonly used to automate sample delivery in atomic spectroscopy workflows to improve data quality and throughput.
- AIM Autosamplers are well‑suited for spectroscopy applications requiring:
Routine, high‑volume elemental analysis - Environmental, industrial, or QA/QC laboratories
- Methods with fixed sequences and repeatable uptake requirements
Manual sampling remains appropriate for:
- Method development
- Very low sample counts
- Non‑routine or exploratory analyses
