Replacing Settle Plates with Active Air Sampling
- Details
- Created: Monday, 12 October 2020 12:14
Settle plates were adequate in the past to meet regulations, but the new approach requires active air sampling.
Active Air Sampling for settle plates by Particle Measuring SystemsThe most universally applied method for cleanroom classification is the one suggested in 1963 by Federal Standard 209 of the USA. In this standard the number of particles equal to and greater than 0.5 µm is measured in one cubic foot of air. This count is then used to classify the room (1 particle = class 1; 10 particles = class 10…). In the same period, scientific publications concerning healthcare facilities suggested that airborne particles carrying micro-organisms associated with human disease were usually found in the 4-20 µm equivalent diameter range. This contamination can be detected by settle plates.

Micron Scientific offer local calibration and service on most of the instruments we supply. We are frequenlty contacted by competitor users to calibrate their equipment. Especialy in South Africa it is important to ask your service providor before you purchase a new laboratatory instrument if they will service and calibrate it locally or send it overseas for calibration.

The PAMAS GMBH SBSS particle analysing system is a tried and trusted measuring instrument for laboratory particle counting. Using measuring data provided by fluid samples with known particulate contaminant, PAMAS has proved the repeatability of its particle counting systems.
Comparison of repeat measurements clearly show that the results of different measurements of the same fluid sample scarcely deviate from one another. Many renowned laboratories appreciate the extremely high measuring accuracy of PAMAS particle counters and in turn, manufacturers of conventional particle counters use the PAMAS SBSS particle analysing system as a reference for their calibration.

Recently I had the opportunity to use a Pamas SBSS ( Syringe Bottle Sampling System) at a customer. The instrument is the flagship liquid particle counter from Pamas GMBH.
What struck me immediately is how easy the instrument is to use! I am so used to controlling an instrument via software and PC these days, it is almost a novelty to just control the instrument via a touchpad!
It has a simple menu system that allows the user to operate the instrument directly ( ofcourse normal software control via PC is also possible).

Data Trending and Alert/Action Levels definition are new requirements in the latest EU GMP Annex 1, Revision 12 draft. Trends allow you to quickly and easily identify changes in your cleanroom data and leverage this to make effective decisions, changes, and adjustments often before problems occur. Here we discuss three key components in the latest Annex 1 draft:

Have you ever tried to perform particle measurement of therapeutic protein solutions? You will encounter several challenges. There is extremely limited sample available because therapeutic protein solutions are very expensive. In addition, the samples are usually highly viscous. How can reliable values be measured without diluting the samples or having to resort to the subjective and time-consuming microscopic analysis?

The properties of superhydrophobic surfaces are highly desirable in many industries and applications. Unfortunately these surfaces often suffer from low durability. They are for example easily scratched by hard objects and their superhydrophobicity is destroyed.
In the latest Nature cover story Wang, D., Sun, Q., Hokkanen, M.J., Ras, R.H.A. et al. introduce a new strategy to create superhydrophobic surfaces that have a high mechanical stability. They designed a material matrix that combines the superhydrophobic nanostructure with a highly durable macrostructure. This new material can be even scratched with a razorblade or with sandpaper without losing its superhydrophobic properties. Due to its transparent nature the new material matrix is an ideal candidate for a new kind of self-cleaning cover material for solar panels.

Written by Maurizio Della Pietra There is little overlap with cleanroom monitoring and qualification and classification as seen in the image here:
The goal of cleanroom monitoring is to assess the potential contamination risk of the product. The key location focus of monitoring is at the manufacturing processes. The only connection with Cleanroom Qualification is that, as a secondary purpose, we also provide evidence of the performance of a cleanroom from the process point-of-view. Cleanliness classes for oils & fuels
To display particle counts in oil and fuel samples and even water-based hydraulic fluids, in a simplified and uniform way, results are often reported in cleanliness classes according to a specific reporting standard. In the following article we discuss the most common and important international standards. IP PM FA – New test method for the determination of particulate contamination in diesel fuel
In recent years there has been an increase of truck engine breakdowns reported in the South of the UK, the Benelux and Northern Germany. The injection systems of the truck engines had been heavily damaged by contaminated diesel fuel. Deliveries from a refinery in Eastern Europe was identified as the source of this contamination Part 2 of 6 part blog on : Cleanroom Classification – Qualification – Monitoring Per EU GMP Annex 1, rev 12 draft

Cleanroom Classification Which DVS (Dynamic Vapour Sorption) instrument is right for me?
When I look at any range of instruments all performing the same basic function I want to know what makes one model different from another. This is also true of the DVS series ( Intrinsic , Adventure, Resolution and Endeavour). In this short article I hope to make that a lot easier! We know Dynamic Vapour Sorption is simply the measurement of the adsorption or de-sorption of a solvent on a solid material. Materials investigated using DVS includes Pharmaceutical powders, tablets, API’s and excipient materials), Food powders, processed food, biscuits, cement, ceramics, cosmetics, hair care, contact lenses, packaging materials: paper, plastics. Cleaning and Disinfection: the (newest) guidelines from Annex 1, rev 12
The latest Annex 1 draft offers several updated expectations on cleaning, decontamination and disinfection. Definitions Cleaning (NEW)A process for removing contamination e.g. product residues and disinfectant residues. Decontamination The overall process of removal or reduction of any contaminants (chemical, waste, residue or microorganisms) from an area, object, or person.

In this blog series we will examine what a new fill line looks like with and without QbD implemented at the design phase. We will study each critical area of the fill line and the activities necessary to effectively bring the control features into effect. These examples come from real-world applications experienced by the Particle Measuring Systems’ Advisory Services Team. Our team has over 70 years of collective experience working in and advising cleanroom users around the world. Validation of Relative Humidity
