Water Under The Bridge -- In Process Monitoring, Part 2
By Barbara Kanegsberg, Ed Kanegsberg
Manufacturing problems can lead to large costs of rework or can result in product becoming scrap. Immediate detection of problems is a key to increasing productivity and decreasing costs.

Hand Hygiene In Controlled Environments
By Herbert N. Prince, Ph.D.,, Daniel L. Prince, Ph.D.
Studies with topical antiseptics against bacteria and viruses inform the choice of rapid kill agents for hand sanitization.

Trapping Airborne Molecules -- Part 2: Mechanisms
By Barbara Kanegsberg, Ed Kanegsberg
Clean air and gases are critical for many industrial processes.

Airborne Molecular Contamination Part 3 - Head It Off
By Barbara Kanegsberg, Ed Kanegsberg
AMC can be a “silent poisoner” of your process. Poisons sap strength — including product quality and profits.

Airborne Molecular Contamination, Part 2: Detecting AMC
By Barbara Kanegsberg, Ed Kanegsberg
"How do I know if I have AMC?" Hopefully, you are not suspicious of airborne molecular contamination because of poor yield or customer complaints

Airborne Security
By Frank Stamatatos, Aaron Ayer
Particles in a cleanroom environment must be removed. Particles that can reproduce themselves can become a difficult part of the problem to address.

Sources of Viable Contamination and Update on Cleanroom and Controlled Environmental Standards
By John Broad, Barbara Kanegsberg, Ed Kanegsberg
While not all organisms are harmful, minimizing viable contaminants is generally desirable. Such contamination may include bacteria, fungi, algae, protozoa, and viruses.

Testing Compressed Air Lines For Microbiological Contamination
By Rudy Pina
An air impaction microbial assessment of your air supply may indicate you have unwanted inhabitants in your compressed air system.

Instantaneous Microbial Detection
By Chuck Bolotin
An optical technology has been developed that can determine the quantity and size of particles in liquid or air, and simultaneously determine whether each particle is inert or biologic, all in real time.

Effects of Moisture on the Purification of Compressed Air
By Russel J. Holmes, Daniel Alvarez, Jr., Joseph Rotter, Allan Tram
A method was developed to measure hydrocarbons to 1 part-per-trillion (ppt) concentration levels with a gas chromatograph and flame ionization detector (GC/FID). This method was used to measure purifier siloxane removal efficiencies from air under both dry and humid conditions.

Pharmaceutical Industry Cleanroom Monitoring: Viable and Non-Viable Particle Detection
By Jason Kelly
Let us take a closer look at the way the cleanroom environment is monitored to verify the existence or nonexistence of particles both viable and non-viable.

Microbial Monitoring of Controlled Environments and Alert and Action Limits
By Matthew Hanson, Gregg Mosley
This article is written in order to address some areas of misunderstanding within the medical manufacturing industry regarding measurements of microbial contamination in cleanroom theaters as promoted in some documents.
