How to Achieve Quality by Design (QbD) in a new Pharmaceutical Fill Line: Intro and Regulatory (Series Part 1 of 6)

courtesy of Maurizio dellapietra

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.

What is a colloidal dispersion and how to measure its stability?

adobestock 110jpegcolloidal 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.

Agrochemical Formulations

courtesy of Formulaction

Agrochemicals, such as fertilizers, and pesticides are big businesses. Since 2012total 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

On Demand Webinar - Understanding ISO 14644-2:2015 Cleanroom Monitoring"


Are you sometimes confounded by all the regulatory standards for Pharma cleanrooms?! You're not alone! That's why we created the Webinar: "Understanding ISO Standards: 14644-2:2015 Cleanroom Monitoring".


If you have a couple minutes today, watch it here:

21 CFR Part 11 and Data Management for Data Integrity

21 CFR Part 11

21 CFR Part 11 and Data Management for Data Integrity

21 CFR Part 11 is the most widely used standard for appropriate data management. Part 11 applies to records in electronic format that are created, modified, maintained,
archived, retrieved or transmitted according to requirements set in FDA regulations. Electronic records/signatures that meet Part 11 requirements may be used in lieu of paper records.

The document is divided into three parts:

  1. Electronic Records
  2. Digital Signatures
  3. Audit Trail

Product Focus : RHEOLASER Master

rheolasermaster191141The RHEOLASER Master is an instrument that uses a technique called MS-DWS ( Multi-Speckle Diffusing Wave Spectroscopy) to probe the visco-elastic properties of a liquid or gel-like sample.

What is MS-DWS?

Multi-Speckle Diffusing Wave Spectroscopy is a technique that uses a ligh source to track the change in postion of tiny particles in a liquid or gel . From this movement a displacement curve over time is polotted which in turn in used to calculate elasticity , liquid/ solid like behaviour. gel point  and the viscosity index of samples. Learn More

The Pamas SBSS - a user perspective

SBSSvidRecently 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 immediatly is how easy the instrument is to use ! I'm so used to controling  an instrument via software and PC these days, it is almost a novilty!  It has a simple menue system that allows the user to operate the instrument directly ( ofcourse normal software control via PC is also possible).

Dynamic Vapour Sorption

Dynamic Vapor Sorption (DVS) is a gravimetric sorption technique that measures how quickly and how much
of a solvent is absorbed by a sample: such as a dry powder absorbing water. It does this by varying the vapor
concentration surrounding the sample and measuring the change in mass which this produces. Water vapor is most
commonly used, but it is also possible to use a wide range of organic solvents.

New development from PAMAS the S50DP particle counter

PAMAS S50DP: The Particle Counter With Integrated Dilution System For Fluid Analysis

The PAMAS product range includes measuring instruments for long-term condition monitoring of liquids like hydraulic or lubricating oil or for contamination analysis of particulate matter in water, pharmaceutical suspensions and many other fluids.

The newly designed PAMAS S50DP has been specifically designed for fixed online measurement of dark fluids.
This online particle counter automatically dilutes dark sample fluids prior to measurement with its integrated dilution system , thus reducing the sample’s turbidity level. Fluid cleanliness (e.g. of oil, water or fuel) can be monitored through optical particle counting. An automatic particle counter detects and measures particulate contaminants in the fluid.
