Laser plays an important role in particle measuring and Particle
Measuring Systems (PMS) — the first manufacturer to build a laser-based
particle counter, owns much knowhow in extending laser life.
To build high quality particle counters with reliable and
long-lasting laser, PMS first began by sourcing for laser with proven
reliability and longevity. Next, PMS assured the longevity of the operating
laser by developing and using their very own patented cooling system in their
products, including the Lasair® particle counters.
Later, PMS also derated the operating power of their laser to
prolong the lifespan of the laser diode while maintaining the performance of
their particle counters. These may sound simple, but they also reflect PMS’s
dedication to deliver the best measuring equipment through their extensive and
vigorous research.
Next, instead of simply quoting the MTTF of the laser diode
used in a particle counter which can be misleading for those who plan to
purchase a new particle counter, PMS’s research on laser diode is well
documented with field data as evidence.
The Lasair® Pro aerosol particle counter is the fourth generation of the Lasair® family – a series of laser-based aerosol particle counter known widely for its long-lasting laser.

Particle Measuring Systems (PMS) specializes in viable and nonviable particle counters and particle counting solutions that measure and monitor contamination levels in clean and controlled environments. Since 1972, PMS knowledgeable and experienced team has been developing innovative technologies to advance the cleanroom monitoring industry. Led by PMS technology which provides accurate and reliable results and information for clients, Particle Measuring Systems is one of the world’s leading companies and manufacturers for particle counting instruments, and molecular and microbial monitoring.
A cleanroom is a controlled environment to manufacture products to help improve yield and meet regulatory requirements. Particle Measuring Systems (PMS) lead this industry of cleanroom particle counters and contamination monitoring worldwide by actively developing their instruments to perfection. Anything less is unsatisfactory.
As part of Particle Measuring Systems (PMS) complete clean environment monitoring solutions (products and services), PMS provides you with Airborne Molecular Contamination (AMC) solutions.
In high-tech ultra-clean manufacturing processes, AMC can cause costly damage. PMS’s AMC monitors detect acids, amines, ammonia, and chlorides, helping you quickly identify problems and their location before your product is contaminated.
In this webinar, you will learn from our Speaker Jeff Lee on what is the molecular contamination and why is this important, sources and effects of molecular contamination, monitoring technologies and AMC monitoring strategies. Don’t miss out this golden opportunity!

Particle Measuring Systems (PMS) is proud to present the latest in their flagship line of Lasair airborne particle counters. The Lasair Pro supports a complete contamination control solution including clean area monitoring (portable and remote) while meeting global requirements for data integrity. Designed for intuitive and reliable aerosol particle counting, this newest addition to the PMS fleet supports a variety of applications while meeting, and anticipating future, international cleanroom certification standards.
Designed to be easy to use, the multi-gesture touch screen interface and intuitive menu guide you through logical navigation, provide effortless learning and simple configuration. Additionally, it was specifically engineered for use where sanitization is required; the exterior of the Lasair Pro airborne particle counter can be easily cleaned using a wide variety of disinfectants and cleaning agents.
The Lasair Pro is highly adaptable, allowing you to program and manage all sampling activities locally or remotely. The unit can store up to 10,000 data samples and the collected data is securely saved and transferred meeting data integrity related standards such as FDA 21 CFR Part 11 and EU GMP Annex 11. Additionally, you can securely configure up to 100 users on each instrument or use the NFC card capabilities for unlimited users.

Data integrity in Pharmaceutical industries has become hottest topic since past few years but many of Pharma company are still struggling in adapting to this new regulation. The major challenge normally is the difficulty to alter from the existing quality system which involve new method of data collection from various sources, validation and as well to maintain the integrity throughout the process.
Aside from data integrity, cleanroom certification regulations will be covered as many of us confuse the certification and monitoring. The requirement of new Annex1 (draft revision) has clearly defined this two activities and it should be implemented into your quality system.
In this webinar, you will learn from our Speaker Paul Hartigan what is the requirement of Data Integrity and cleanroom certification regulations and how to implement it in the simple and easy manner by using PMS latest solutions. Don’t miss out this golden opportunity!

COD is a measure of the oxygen equivalent of the organic matter in a water sample that is susceptible to oxidation by a strong chemical oxidant. COD is widely used as a measure of the susceptibility to oxidation of the organic and inorganic materials present in water bodies and in the municipal and industrial wastes. The COD test of natural water yields the total quantity of oxygen that is required for oxidation of a waste to carbon dioxide and water. In a BOD test, only biologically reactive carbon is oxidized while in a COD test, all organic matter is converted to carbon dioxide. The test for COD does not identify the oxidizable material or differentiate between the organic material and inorganic material present. Similarly, it does not indicate the total organic carbon present. Consequently, the COD values are higher compared to BOD. Nevertheless, COD is a useful variable that can be rapidly measured; the COD test can be performed in 3 hours against 5 days required for a BOD5 test.
What are the applications of COD testing?
COD is often used as a measurement of pollutants in water, wastewater, and aqueous hazardous wastes. One application of the COD test is to measure soluble COD in wastewater, since characterization of total COD in wastewater is critical for accurate modeling of biotransformation in wastewater treatment processes.
Another application is to rapidly infer biodegradability of samples from the COD tests. This is commonly accomplished by establishing a correlation between COD and BOD. This method has been found successful when the proportions and types of materials in a wastewater remain relatively constant.
Why must we perform COD test?
In Malaysia, the Environmental Quality Act 1974 states that the owner/occupier of a premises shall conduct performance monitoring of the components of the effluent treatment system in the manner as specified in the Guidance Document on Performance Monitoring of Industrial Effluent Treatment Systems issued by Department of Environment; and equip himself or itself with facilities, relevant equipment or instruments for the purpose of conducting performance monitoring of effluent. Acceptable conditions for the discharge of industrial effluent or mixed effluent for parameter of Chemical Oxygen Demand (COD) must conform to standard A and standard B as per the Seventh Schedule and Eighth Schedule of the Environmental Quality Act 1974. The standards are as follows:
