Mark & Wedell Auto-Samplers: Solids Auto-Sampling: Methodologies & Techniques

Sampling is a critical process in various industries, including pharmaceuticals, food and beverage, environmental monitoring, and mining. Accurate and representative sampling of solids is particularly challenging due to their heterogeneous nature. Mark & Wedell Auto-Samplers offer innovative solutions for solids auto-sampling, ensuring reliable and efficient sample collection. In this article, we will explore the methodologies and techniques employed by Mark & Wedell Auto-Samplers to address the complexities of solids sampling.

The Importance of Solids Sampling

Obtaining representative samples of solids is crucial for quality control, process optimization, and compliance with regulatory standards. Inaccurate sampling can lead to misleading results, compromising product quality, safety, and profitability. Solids can vary in composition, particle size, and distribution, making it challenging to obtain a representative sample manually.

Automated Solids Sampling with Mark & Wedell Auto-Samplers

Mark & Wedell Auto-Samplers offer advanced solutions for automated solids sampling, ensuring accuracy, repeatability, and efficiency. Their auto-samplers are designed to handle a wide range of solid materials, including powders, granules, pellets, and even sticky or cohesive substances.

1. Sampling Methodologies

Mark & Wedell Auto-Samplers employ various methodologies to ensure representative solids sampling:

• Incremental Sampling: The auto-sampler collects small increments of the bulk material at regular intervals, ensuring a representative sample. This method is particularly useful for materials with heterogeneous compositions.
• Composite Sampling: The auto-sampler combines multiple incremental samples to create a composite sample. This approach reduces the impact of spatial variations within the bulk material, providing a more accurate representation of the overall composition.
• Random Sampling: The auto-sampler uses a random sampling algorithm to collect samples from different locations within the bulk material. This method helps minimize bias and ensures a representative sample.

2. Sampling Techniques

Mark & Wedell Auto-Samplers employ various techniques to overcome the challenges associated with solids sampling:

• Auger Sampling: The auto-sampler uses an auger mechanism to penetrate the bulk material and collect a sample. This technique is suitable for cohesive or sticky solids.
• Vibratory Sampling: The auto-sampler utilizes vibration to facilitate the flow of solid particles, ensuring consistent and reliable sampling.
• Gravity Sampling: The auto-sampler relies on gravity to collect samples from a flowing stream of solids. This technique is commonly used in continuous manufacturing processes.

Case Studies: Real-World Applications

Mark & Wedell Auto-Samplers have been successfully implemented in various industries. Let’s explore a few case studies:
