Replacing Settle Plates with Active Air Sampling
- 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.

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.
The Pamas SBSS - a user perspective
- Created: Wednesday, 16 September 2020 11:17
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).

Particle measurement of therapeutic protein solutions
- Created: Monday, 13 July 2020 11:42
text supplied courtesy of PAMAS
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?
Design of robust superhydrophobic surfaces

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.

Part 3 of 5 part blog on : Cleanroom Classification – Qualification – Monitoring Per EU GMP Annex 1, rev 12 draft
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

Product Focus: RHEOLASER Crystal
Looking at the technical description of the RHEOLASER Crystal it tells us it is a new thermal analysis instrument that can detect changes in the microstructure ( phase transition, melting or crystallisation ) of a liquid or solid sample. What does that actually mean in practise, and how is that information useful ? In this short article I will attempt to explain that.
Turbiscan Classic, Lab , Tower or AGS - which model is best for me ?
Looking at the 4 models ( Turbiscan Classic 2/ Lab/ Tower/ AGS) it is easy to get confused and the natural question is to ask which model is best for me ? This article will attempt to give greater clarity on the differences between the models and the unique features each model offer.
All 4 models scan a liquid or paste sample for instability by detecting very small changes in sample concentration or size in tiny slices of the sample in a glass tube. This technology (invented by Formulaction back in the 1990's) offers an objective, reliable and above all quick way to decide if a product or formulation is stable or unstable. In most cases product stability is determined in 2 to 5 days at most. Multiple measurements is made over minutes to hours (depending on the sample).
Product Focus: Wipfrag 3
I receive regular enquiries about Wipware fragmentation analysis software Wipfrag 3.0 and which platform ( windows, apple IOS, Android (coming soon)) to use.
I will try to explain the diffrences in this short article. What I like about this technology is that allows the use ro get a size distribution of an good image just using software without the hassel (and potenital risk working at a rockpile) of sieving.
If you had quick look at the technology you will understand it a relatively simple process of capturing an image, loading it into the software and then fine tuning some threshold settings before generating a size distribution. Editing of the image is also possible to include or ignore particles etc….
The software on all the platforms looks exactly the same so where do the differences come in?
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.

What is a colloidal dispersion and how to measure its stability?
A colloidal dispersion is composed of solid, liquid or gas particles dispersed in a continuous phase (solid, liquid or gas). Strictly speaking, the term colloidal refers to particles with at least one dimension ranging from 1nm to 1µm. Most commonly encountered colloidal dispersions are solid-liquid (suspensions), liquid-liquid (emulsions), gas-liquid (foams), and solid-gas (aerosols) dispersions.

Agrochemicals, such as fertilizers, and pesticides are big businesses. Since 20121 total pesticide sales have remained relatively stable within the EU, with over 300M kg of pesticides alone being sold in 20162. The market has been moving towards growing demands of organic nutrition and higher concentration pesticides. Reducing our dependence on agrochemicals without posing risks to food security is challenging because pesticides, fertilizers and growth hormones all help to ensure improved and consistent crop yields.3
