River Microplastics Detection Methods And Solutions

1. Teacher Chen’s Challenge: River Microplastics Detection Has Become a Bottleneck in the Research Project

A team led by Teacher Chen from the School of Environmental Science at a university in southern China is currently planning to apply for a research project on regional river management, in which river microplastics detection, continuous monitoring, and tracking analysis are core technical components. How to select an efficient, stable, and standardized microplastics detection method directly affects the quality of subsequent research data and project progress.

At present, the team uses a semi-automatic Fourier microplastics analyzer. However, when conducting river microplastics detection on a large number of samples, the equipment has revealed three major bottlenecks:

BottleneckSpecific PerformanceImpact on Research
High Labor CostsLarge-scale water sample testing requires significant manpower, with very low daily processing capacity per personThe team’s energy is occupied by basic testing work and cannot focus on core research
Long Detection CycleThe entire process for a single sample takes 3-4 hours, with a maximum of 2-3 samples detected per person per dayThe project schedule is seriously delayed, making it difficult to meet research milestones
Poor Data ConsistencyMultiple processes, including particle screening, spectral detection, and data statistics, rely on manual operationsHuman errors are difficult to avoid, affecting the reliability of river microplastics detection data and the quality of research papers

For research teams that need to conduct long-term river monitoring, traditional microplastics detection methods involving extensive manual operations not only reduce detection efficiency but also increase the risk of data deviations in batch sample testing.

After being introduced by peers, Teacher Chen proactively contacted AIMOLI to learn more about the technical features and applicability of the AML518 fully automated microplastics analyzer in river microplastics detection.


2. Current Status of the Domestic Microplastics Analysis Industry: Limitations of Traditional Microplastics Detection Methods

2.1 The “General-Purpose” Dilemma of Imported Equipment

At present, imported equipment still dominates the domestic microplastics analysis market. However, some imported equipment is essentially general-purpose optical instruments, rather than being specifically developed and designed for microplastics detection scenarios.

In traditional microplastics detection methods, most processes, from sample pretreatment and particle screening to spectral detection and data statistics, still require manual operation. Although the equipment can perform basic area scanning, too much manual involvement in river water sample testing directly extends the river microplastics detection cycle.

Therefore, for projects involving river management and long-term environmental monitoring, selecting a more automated microplastics detection method can reduce manual operations, improve batch sample detection efficiency, and enhance data consistency.

2.2 Comparison of Three Mainstream Microplastics Detection Methods

Different microplastics detection methods have different detection ranges, technical characteristics, and application costs. Common methods mainly include infrared spectroscopy, pyrolysis-GC-MS, and Raman spectroscopy.

Detection TechnologyDetection RangeMain LimitationsApplicability Assessment
Infrared SpectroscopyCannot identify particles below 10μmRequires complex dry-film preparation, with high equipment procurement and maintenance costsSmall particles may be missed, with a high cost threshold
Pyrolysis-GC-MSCan detect microplastics at the nanoscaleExtremely high equipment cost and complex operation, making it difficult to popularizeSuitable for research-level applications, not suitable for routine monitoring
Traditional Raman SpectroscopyCan perform wet-state detection with simple pretreatmentLow level of automation, with room for improvement in accuracyPreferred technical approach, but requires automation upgrades

From the perspective of actual river microplastics detection requirements, different microplastics detection methods need to be comprehensively evaluated based on detection range, sample processing, automation level, detection efficiency, and data output capabilities.

Traditional Raman spectroscopy offers advantages such as wet-state detection and simple pretreatment. However, without an automated detection process, it remains difficult to meet the needs of large-scale river microplastics detection. Therefore, combining Raman spectroscopy with an automated system is an important technical approach to improving microplastics detection efficiency.

2.3 Three Major Pain Points of Semi-Automatic Fourier Equipment

Highly dependent on manual operation, time-consuming and labor-intensive: Traditional microplastics detection methods require researchers to participate in sample detection and data analysis. Manual screening, instrument testing, and data calculation all require human involvement. A single sample takes 3-4 hours to detect, and one person can process a maximum of 2-3 samples per day, making it difficult to meet the requirements of large-scale river microplastics detection.

Repetitive work reduces research efficiency: Researchers spend a significant amount of time on repetitive microplastics detection work, making it difficult to devote more energy to research projects, experimental innovation, and data analysis. For research projects requiring long-term river monitoring, detection efficiency directly affects overall research progress.

High operating threshold limits personnel availability: Some imported equipment uses an entirely English operating system, requiring operators to have at least a CET-6 English level. Only highly educated research personnel such as graduate students and doctoral students can operate the equipment independently, which limits team staffing and increases the operational threshold of traditional microplastics detection methods.
