The ARChem SPARC Pay-per-Use Plan

Since inception, the SPARC calculator and this website have been supported by numerous private and government grants that allowed us to consistently bring users a very reliable calculator and website, including almost constant maintenance and customer support. Our customers expected a quality and reliable calculator and we are proud to have delivered for many years.

SPARC has evolved into a very sophisticated calculator that is used and appreciated monthly by thousands of companies, universities and individuals. Unfortunately, as use of the site grew, grants have been reduced and, in order to continue delivering the service users expect, the company needs to institute a small charge for use of the calculator beginning June 1, 2013. Of course we understand the pressures on customer budgets and will keep the charges reasonable, remaining always mindful that our customers demand a superior product, supported by the continuous, excellent and friendly service they have come to expect.

Various plans are available, from single use calculations up to private, proprietary installations for corporate users. Our Sales Director will be happy to provide information for your specific needs. If you would like us to contact you immediately, please email sales (sales@archemcalc.com) and you will be contacted by the Sales Director within 24 hours.

Realizing many present and potential customers have budget considerations, our company is pleased to offer a limited number of free calculations for all users. Our sales coordinator will be pleased to explain this program.
