Continuous Microbial Monitoring For Pharmaceutical Waters

continuous on-line microbial monitor for pharmaceutical waters
Monitoring process water microbial counts in the pharmaceutical industry has traditionally been a time consuming, hands-on operation. Sample preparation, plate counting, stains, reagents, and the time required to get results has kept microbial monitoring a cumbersome task that provides only snapshots of the process water quality at the time of sampling.

Mettler Toledo has introduced its Model 7000RMS, a continuous on-line microbial monitoring system for purified water and water for injection. The system uses advanced laser based technology to provide immediate detection and quantification of microorganisms. Particles as small as .52 microns can be detected, and the monitor uses recent advancements in spectroscopic technology to differentiate between microbial and inert particles.

The 7000RMS puts on-line analytics for microbial contamination on the same timeline as TOC and conductivity, with all three critical aspects now subject to real time measurement.

The white paper included below delivers a deeper and more detailed view of the technology and the how the system works. Detailed application and product information is available from product specialists.

Thermal Oxidation Applied For Emissions Control

Pollution control - Part of successful plant operation
Thermal oxidation is a process employed in a number of diverse industries as a means of pollution and emissions control. Essentially, the process uses heat to promote the breakdown of hazardous air pollutants and volatile organic compounds into less harmful byproducts. Many pollutants are hydrocarbon based and when properly processed will oxidize efficiently and provide an output consisting primarily of H2O and CO2.

The process employs a number of inputs, aside from the subject pollutant stream. A fuel input is needed to maintain the elevated temperature that will force oxidation of the pollutants. Being essentially a combustion operation, there are opportunities to boost efficiency and minimize the expenditure for the fuel inputs. Heat recovery is an essential element of achieving high efficiency levels. This can take many forms, depending upon what the energy needs of the facility might be. One option is a waste heat boiler to produce steam for other plant operations. There are many other options which will be discovered with a thorough review and analysis of the plant operations.

Process Combustion Corporation, a recognized manufacturer of oxidation technology, defines thermal oxidation, as it applies to pollution and emissions control, like this:
Thermal oxidation is the effective employment of a process that provides thorough mixing of an organic substance with sufficient oxygen, at a high enough temperature, for a sufficient time, to cause the organics to oxidize to the desired degree of completion.
Achieving effective utilization of a thermal oxidation system requires the application of experienced engineering talent.

Specific Gravity Analyzer for Fluid Process Applications

specific gravity analyzer for industrial process liquid
Speicifc Gravity Analyzer
Specific gravity is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume (Thank you, Wikipedia).  Often the reference substance for liquids is pure water at a temperature of +4°C, which is assigned a value of 1.0. The specific gravity measurement is used throughout many industries as a measure of concentration in a solution. An example would be the concentration of sugar in a solution of water and sugar. 

For purposes of process analysis, an instrument providing continuous measurement is generally advantageous since its operation accommodates the changing nature of the process. One device employs two tubes and a calibrated float to provide a continuous display of a liquid's specific gravity. Liquid from the process fluid sample line enters the bottom of the inner tube containing the float. A very small sample flow rate is needed. The float is calibrated for the subject process liquid and has a reference scale from which the specific gravity is manually read. The sample fluid overflows the inner tube, collecting in the outer tube where it is drained away. The continuous, though small, flow of sample liquid enables each reading to reflect the current process condition.

This simple and effective instrument provides accurate measurement and requires little maintenance. Share all your process fluid analysis challenges with application specialists. Combine your process knowledge with their product application expertise to develop the most effective solutions.
