Bioanalyzer tips (from Agilent)
1. Electrode cleaning. All assays are sensitive to voltage variations caused by residue on the electrodes. Results can be erratic due to dirty electrode pins.
a. Remove chips promptly after each run and use the cleaning chip
b. Clean monthly or sooner if the electrode is suspected to be dirty.
c. For models G2938B and C, remove the electrode from the cassette and soak 15 min. in DI water or RNAse free (if RNA assays are employed).
d. The electrode is not removable from the cassette on model A instruments so remove the cassette & clean as well as possible without getting the cassette wet. e. Sonicate or use a soft toothbrush gently
f. RNAse ZAP (for RNA assay users).
g. Rinse well; final rinse with 100% EtOH; dry 2 hrs.
2. Prime properly. While being a robust platform, priming issues can crop up even with seasoned users.
a. We recommend having a Priming station maintenance kit on hand (G2938-68716).
b. Change the syringe with each new kit.
c. Make sure that all users follow the priming sequence verbatim. If anyone alters it, they may get some backflow into the station orifice, which will likely give erratic assay results.
d. Inspect the white O-ring on the bottom of the station orifice. Clean or replace as needed.
e. If the orifice may be dirty, use an old syringe to run clean water and then EtOH through the orifice and into the sink. Let dry.
3. Prep the chip
a. Let reagents warm up to room temperature, vortex, and give a quick microfuge spin. Get all reagents and samples ready before priming.
b. Protect the dye and gel-dye mix from light.
c. Generally 2000 rpm is enough and avoids some issues of flicking liquid out of the wells. If your vortexer top is worn, an improved one is available (part 5022-2190).
d. Have the chip loaded and running within 5 to 10 minutes of priming.
5. Infreq. Users. You may make smaller batches of gel-dye mix, but would need extra Corning Spin-X 0.22 um filter tubes (our part 5185-5990). If your reagents expire, you may purchase reagents without chips for about half the cost.
6. Avoid contamination. To avoid dust and other confounding contaminants: wear powder free gloves, don?ft handle the bottom or top of the chips or place on dusty surfaces. Close the BioA lid when not in use and/or clean the lens with lens paper and 70% isopropanol.
7. Exploit the software. Expert software has many features and a very extensive help menu. Click through the toolbar menu options and the Setpoint Explorer.
8. Explore the possible. Agilent is continually coming up with assays for the Bioanalyzer and users perfect their own independently or in collaboration with Agilent. We maintain a listing of published paper available upon request. Also consult our web library at http://www.chem.agilent.com/Scripts/PCol.asp?lPage=50

Maintenance and Troubleshooting
1. Chip not detected. The gaskets and o-rings in the priming station need to be replaced. Apparently if the priming station isn’t working properly, the liquid level in the chip isn’t right, and the chip isn’t detected.
