The Ignitable Liquids Reference Collection is a compilation of reference materials used by forensic analysts to conduct fire debris analysis. The ILRC consists of a comprehensive set of ignitable liquids with accompanying characterization data used in the analysis of fire debris in accordance with the American Society for Testing and Materials (ASTM) E-1387 and E-1618 standard test methods. Samples from the ILRC repository can be purchased from NCFS using the ILRC Order Form. All samples will be delivered via UPS-Ground in 1/2 dram vials on activated charcoal. Sample is $5.00 per sample and $7.50 for shipping and handling.

The US Y-STR Reference Database is a searchable listing of 11- to 17-locus Y-STR haplotypes located on the web at www.usystrdatabase.org, was developed by combining data from NCFS with databases from government, commercial, and academic resources throughout the United States. The database provides tools for laboratories to obtain Y-STR haplotype frequencies needed to calculate matching or paternity probabilities with confidence intervals. Other features include the ability to simultaneously upload multiple haplotypes for searches directly from Genotyper® and GeneMapper® text files, the ability to include or exclude sampled populations, and a report-style printout of the results. Samples are divided into five forensically relevant ancestries: African-American, Asian, Caucasian, Hispanic and Native American.

All forensic laboratories and institutions are invited to contribute to the U.S. Y-STR Database. The resulting increase in the database size and the inclusion of geographically and ethnically varied population groups will increase the scientific and forensic efficacy of the database.
