Deciphering the Grade of Cleaning Agents for your Cleanroom-Assembled Products

by Gerbig in General Cleanroom. Comments Off on Deciphering the Grade of Cleaning Agents for your Cleanroom-Assembled Products

High purity solvents are a part of every critical process. They are just as important to critical products as the quality of air. While there is a generally accepted standard for high purity laboratory chemicals, specifications vary among chemicals. Solvent manufacturers offer additional grades, as well. So how do you know whether the solvent is right for you?

Additions to the standards

The American Chemical Society (ACS)’s Reagant Grade meets the minimum impurity specification set by the ACS. This is the generally accepted standard. However, to address requirements of specific standards solvent manufacturers offer grades with additional constraints or specifications. A few examples include:

“Electronic Grade” for electronic assemblies
“HPLA Grade” for liquid chromatography
“Semiconductor Grade” for wafer preparation uses

For these kinds of grades, suppliers may list limits for elements not included in the ACS Reagant Grade. Currently there are no industry-wide standards for specialized … Read More »

Do you Need Routine Maintenance for Cleanroom Gas Detection Systems?

by Gerbig in General Cleanroom. Comments Off on Do you Need Routine Maintenance for Cleanroom Gas Detection Systems?

Gas detection systems not only rescue cleanroom productivity, they also save lives. In the last few years, the technology for these systems has drastically improved. This makes them more reliable, but are they reliable enough to forego the routine maintenance plan?

The average unit for detection costs around $1,000. A maintenance plan also costs around $1000 (annually). With that kind of a price tag, it’s understandable why only about ten percent of facilities with gas detection systems have active maintenance programs.  However, this is a number that has gone up over the past few years. Let’s look at the considerations for maintenance plans.

All gas detection equipment realistically should be tested every 90 days to ensure the safest, most proficient function. A maintenance plan covers this, ensuring everything is calibrated and responding correctly, and that equipment is detecting all target gases. … Read More »

Possibilities for a Greener Cleanroom?

by Gerbig in General Cleanroom. Comments Off on Possibilities for a Greener Cleanroom?

Chemicals, water, and energy consumption are cornerstones of nearly all cleanroom processes. They are also the three areas that most affect the “greenness” of these operations. Reducing the use of any of these would certainly result in cost savings for companies. The question is: how plausible is to alter these things and still leave the process effective and efficient?

In manufacturing, we question how holistic regulations will affect production schedules, product quality, risks to employees, and damage to the environment. Implementing green practices are sure to change chemicals and/or processes that affect these four areas. As much as businesses support green processes, accepting changes depend greatly on their impacts to the operation as a whole.

Controlled Environments writers Barbara Kanegsberg and Ed Kanegsberg interviewed experts about the challenges and possibilities of a green, safe and sustainable future in “2020 Vision: Green, … Read More »

5 Tips to Make your Life Easier When Choosing a Cleanroom Filter

by Gerbig in General Cleanroom. Comments Off on 5 Tips to Make your Life Easier When Choosing a Cleanroom Filter

Your cleanroom is nothing without your air filtration system, and your filtration system is nothing without the right filter. The right filter, however, is not simply the one that fits and cleans the air to compliance. The right filter will spare you energy and headaches down the road. Here are a few things you should know before buying a filter that will help you later:

Know how it’s been tested. Your filter should be tested according to application, and you want to make sure that each filter is tested individually. If the filter was only batch tested, you cannot be sure of its quality.
Some filters save energy. The less resistance to airflow your filter has, the less energy is required to move the air. Deep-pleated filters offer a number of benefits in energy consumption. They increase the filter media size and … Read More »
