Our good friend, Ron Moore, Esquire writes us “I actually had a client researching lawyers who looked at the Truth About Forensic Science geek of the week posts and liked my answers. It made a difference in who he decided to hire. Thanks!” So, there is a lot of value in www.TheTruthAboutForensicScience.com Forensic Science Geek of the Week Challenge. Try it out today.
Forensic Science Geek of the Week
- Forensic Science Geek of the Week
Thanks to the combined inspiration of Christine Funk, Esquire and Chuck Ramsay, Esquire, a new twist of this blog is being introduced. A weekly fun forensic science challenge/trivia question. The winner will be affectionately dubbed “www.TheTruthAboutForensicScience.com Forensic Science Geek of the Week.”
Rules:
- The challenge will be posted Sunday morning 12 noon EST.
- Answers to the challenge will be entered by responding to this blog post or the www.TheTruthAboutForensicScience.com FaceBook fan page.
- All comments that are answers to this blog will released after 9pm EST.
- The first complete and correct answer will be awarded the envious title of “www.TheTruthAboutForensicScience.com Forensic Science Geek of the Week”
- “www.TheTruthAboutForensicScience.com Forensic Science Geek of the Week” is entitled a one time post of his/her picture on this blog and the www.TheTruthAboutForensicScience.com FaceBook fan page. The coveted title will be his/her for that week. Additionally, a winner will be allowed one link to one webpage of his/her choice. Both the picture and the weblink is subject to the approval of Justin J McShane, Esquire and will only be screened for appropriate taste.

Mehul B. Anjaria says:
This is an analytical balance. It is used in laboratories to weigh substances such as drugs or chemicals. Note that the weighing area is enclosed so that wind drafts do not affect the weighing. Also it must be on a completely level surface for accurate measurements.
The best way to calibrate this instrument is to have it performed by a firm that is accredited to perform calibrations per ISO guidelines. The calibration essentially involves using weights that are traceable standards. The weights of course must be within the range of the balance and include amounts typically weighed on the balance. Typically this calibration is performed at least annually.
The readings are critical in forensic science, since for example, specific quantities of street drugs may result in enhanced sentences. Also, quantitative analyses depend highly on accurate amounts of input chemicals.
In the present day of ISO accreditation, it is also important to determine what the measurement uncertainty of the device is. In other words, what is the range that the device may report around a ‘true’ value.
Ron Moore says:
This is an analytical balance. It is used to weigh things, like drugs or bullets. It is best calibrated by a professional calibration technician, like the one I used to have on contract to calibrate all the balances in my lab. He would bring a set of NIST traceable weights spanning the usable range of the balance, weight them multiple times on the balance, and give me a certified calibration report for each balance.
